▼ Research into nanomaterials has become more and more popular because of their unique properties compared to bulk materials. Amongst various functional materials, zinc oxide (ZnO), with a direct electron energy band gap of 3.34 eV at room temperature, is an important optoelectronic material with an intrinsically n-type semiconducting property. However, to form a p-type ZnO semiconductor is still a challenge. Copper oxide (CuO), compared to ZnO, has a much smaller band gap, 1.2 eV, and shows an intrinsically p-type semiconducting property. It has been suggested that when CuO is alloyed with ZnO properly, a p-n semiconductor heterojunction can be formed to be utilized in solar cell and gas sensor applications. In this thesis, ZnO/CuO core-shell nanowire arrays have been successfully fabricated by a simple three-step process. ZnO nanowire arrays were first grown by the hydrothermal method using ZnO seeded substrates. Copper then was deposited on as-grown ZnO nanowire arrays by a DC sputtering method. Thermal oxidation of copper nanofilm was utilized to enable the formation of ZnO/CuO core-shell nanowire arrays. The Cu nanofilm thermal oxidation behavior on the three-dimensional (3D) ZnO nanowire arrays was systematically studied by introducing different oxygen flows and different pressures. It has been suggested that increasing oxygen flow rate might increase local partial oxygen pressure, thereby increasing the degree of oxidation throughout each single ZnO/Cu core-shell nanowire. Higher pressure might favor the formation of Zn₂SiO₄ at the interface of ZnO and silicon substrates. ZnO/CuO core-shell nanowire arrays have exhibited better absorption efficiency in visible region as compared to the pure ZnO nanowire arrays, which suggests that ZnO/CuO core-shell nanowire arrays have strong potential as nanoscale building blocks in solar cells and light emission devices. In this thesis layout, the first chapter gives general concepts and background on ZnO and CuO nanowires. Chapters 2 and 3 will provide the experimental methodologies and some important parameters to control. Chapter 4 focuses on the results and discussion on the characterization, growth mechanism, and Cu nanofilm oxidation behavior on 3D ZnO nanowire arrays. Chapter 5 concludes this thesis work and provides suggestions for the future work. Advisors/Committee Members: S. Pamir Alpay, Mei Wei, Puxian Gao.

▼ The ability to grow materials in the nanometric size regime with controlled shape and size provide a fundamental synthetic challenge, while allowing for evaluation of such unique nanostructures in multiple applications. In this dissertation, colloidal sodium lanthanide fluoride (NaLnF4) nanocrystals are described with an overall emphasis on i) size control, ii) surface chemistry related towards their applications as nano-bioprobes, and iii) the synthesis and fundamental aspects of epitaxial layer growth generally referred as core-shell nanocrystals. Chapter 1 provides a brief overview on the basic aspects of colloidal nanocrystals. In Chapter 2, synthesis and surface modification of colloidal sodium lanthanide fluoride nanocrystals, epitaxial growth, and their applications in optical and magnetic resonance imaging is reviewed. Chapter 3 describes a phase transfer protocol utilizing polyvinylpyrrolidone and subsequent silica coating of initially hydrophobic upconverting nanocrystals. This protocol is extended in Chapter 4 using end-group functionalized polyvinylpyrrolidone and demonstrates tunability of surface charge and functional groups on upconverting nanocrystals for targeted labeling of human prostate cancer cells. The synthesis of size-tunable NaGdF4 nanocrystals below 10 nm is described in Chapter 5. These nanocrystals are evaluated for their efficacy in magnetic resonance imaging (MRI), and a fundamental insight into the effect of surface gadolinium ions in T1 MRI contrast enhancement is presented. Chapter 6 demonstrates the synthesis of tunable, epitaxial layers on upconverting (core) nanocrystals. A novel synthetic strategy is demonstrated, by deliberate defocusing and self-focusing of differently sized nanocrystals driven by the common physical phenomenon of Ostwald ripening. Utilizing the contraction of lanthanide ions along the series, a fundamental investigation on the effect of compressive/tensile strain epitaxial layer growth is presented in Chapter 7. The fundamental rule of minimal lattice mismatch for epitaxial growth takes into account only the magnitude of mismatch and not the sign of mismatch caused by a compressive/tensile strained layer. A strong asymmetric effect between the compressive/tensile layer growth given the same magnitude of lattice mismatch is observed, demonstrating the necessity of including the sign of mismatch to generate isotropic (conformal)/ pseudomorphic (coherent) epitaxial growth. Finally, in Chapter 8 conclusions and possible future work are discussed. Advisors/Committee Members: van Veggel, Frank C.J.M. (supervisor).

La thèse est consacrée à la synthèse et à l’étude des propriétés des matériaux hybrides inorganique-organique à base de polyaniline (PANI) et de polypyrrole (PPy) avec des nanoparticules TiO2 (rutile et anatase) et SnO2 applicables à détection l'ammoniac et aux amines. La croissance directe du polymère sur la surface des nanoparticules a permis l’obtention de matériaux nanocomposites avec une structure “core-shell” qui diffère du mélange mécanique simple par une distribution plus uniforme des polymères et une interaction plus forte entre les composants source. L’objet de la recherche est le processus de formation de nanocomposites de polyaniline et de polypyrrole avec des oxydes métalliques. L’objectif de la recherche est de révéler les particularités de la formation et les propriétés des matériaux composites nanostructurés à base de polymères conducteurs et nanoparticules d’oxydes métalliques sensibles à l’ammoniac et aux amines. Les méthodes de recherche incluent le RedOx et la surveillance du pH, FTIR et UV-spectroscopie, SEM, TEM, thermogravimétrie, chromatographie liquide, mesures de conductivité et tests de capteurs. La nouvelle approche d’étude de la cinétique du processus de polymérisation de l'aniline par la surveillance simultané du RedOx et du pH du milieu réactionnel a été proposée. Pour la première fois, on a montré l’influence des acides sulfoniques et des oxydes métalliques sur le procédé de polymérisation de l’aniline et les caractéristiques moléculaires du polymère obtenu. En outre, une corrélation linéaire entre le contenu en nanoparticules et la durée réciproque des stades séparés de la polymérisation a été démontrée. Les nanocomposites “core-shell” formés ont une sensibilité à l’ammoniac et aux amines environ 2 fois supérieure à celle du polymère pur. Les nouveaux matériaux développés peuvent être utilisés dans la fabrication de couches actives des capteurs chimiorésistifs.

This thesis focuses on core/shell nanoparticle catalysts including preparation, characterization and testing performance using direct methanol fuel cell. Core/shell were prepared using noble and non-noble metals. Also some core/ shell nanoparticles supported on silica and different types of carbon were prepared as well in this thesis. Non-noble core/shell nanoparticles including novel Co/Ni, SiO2/Ni using three types of silica and novel SiO2/CoFe were prepared by a new modified sol-gel method using hydrazine in alkali media as the reducing agent to reduce metal chloride through two steps process. Parameters such as temperature, pH of solution and reducing agents, were seen to be of great importance in deciding the morphology of the final product as well as the structure of the core/shell catalyst. Core/shell nanoparticles have been successfully prepared for Co/Ni and SiO2/CoFe for first time by choosing the right parameters. This study presents the unique structure which has not been obtained previously for SiO2/Ni catalyst using commercial silica as core. A novel halo shaped structure was the common feature in the catalysts prepared as indicated by TEM. This study presents as well noble Ru/Pt core/shell nanoparticles supported on three types of carbon by a new modified polyol method for first time. The author of this work is not aware of any studies that have prepared Ru/Pt on carbon powder ≤ 50 nm and Ru/Pt on CMWNT previously. This work presents special structure (crown- jewel shaped) for Ru/Pt on Vulcan XC-72 carbon which was not obtained previously for the same catalyst. Selected catalysts were tested using a direct methanol fuel cell. SiO2/Pt core/shell nanoparticles were prepared for the first time by two different methods, namely a new modified sol-gel and polyol methods with novelty structures halo and crown- jewel shaped respectively. Based on the particles size obtained from TEM images, the modified polyol method seems to have a much greater impact on the particles size than the modified sol-gel method. Based on these findings Ru/Pt, Ru/Pt supported on three different types of carbon and Pt supported on CMWNT were prepared using the new modified polyol method. Pt on CMWNT catalyst was synthesized for the first time successfully by a new modified polyol method and all the particles were found to be well dispersed with a narrow size distribution of an average particles size of 3nm. This catalyst gave promising results on DMFC. Pt supported on CMWNT and Ru/Pt supported on Vulcan and CMWNT were used for the first time as electro-catalysts in DMFC to study the effect of the support on the catalytic activity of catalysts. The results show that Ru/Pt on CMWNT gives better performance than the unsupported Ru/Pt and Ru/Pt on Vulcan XC-72. Using Ru/Pt on CMWNT with higher methanol concentration (anode feed) improved the fuel cell power density when compared with the RuPt commercial catalyst.

Research Doctorate - Doctor of Philosophy (PhD)

Recently, the fabrication of organic photovoltaic devices from water-dispersed nanoparticulate materials (solar paint) has attracted increasing interest since it offers the potential of morphological control coupled with device processing in the absence of organic solvents which are toxic to human beings and the environment. However, to date the reported efficiencies of nanoparticulate organic photovoltaic (NP-OPV) devices have been disappointingly low compared to the standard organic photovoltaic devices. This low efficiency reflects a lack of understanding of the structural motif of NP-OPV devices. Furthermore the fabrication conditions used for NP-OPV devices are not well determined as yet. To improve NP-OPV device performance, understanding the structural motive of NP-OPV devices is necessary and OPTIMISED fabrication conditions for NP-OPV need to be determined. By using relevant techniques such as X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning transmission X-ray microscopy (STXM), and differential scanning calorimetry (DSC), we analyse and optimise the conditions for fabricating NP-OPV devices and show a significant improvement in efficiency as compared to previous work. Using calcium and lithium fluoride interface layers between the aluminium and the active layer were also investigated in this project. It is found that proper thickness of the interface also contributes to improving the performance of NP-OPV devices. In this project poly(3-hexylthiophene) (P3HT) is used as the electron donor and phenyl-C61-butyric acid methyl ester (PC61BM), phenyl-C71-butyric acid methyl ester (PC71BM), and indene-C60-bisadduct (ICBA) as the electron acceptors. The highest efficiency of nanoparticle devices fabricated for P3HT:PC61BM is 1.36 %; for P3HT:PC71BM is 2.00 %; and for P3HT:ICBA is 3.29 % which are by far the highest efficiencies reported so far for each system. Moreover an efficiency of 3.29 % is the highest efficiency for NP-OPV devices reported. In this project we also investigate the structural motive of NP-OPV devices and find that for P3HT:PC61BM nanoparticles, the particles are core-shell in nature with a PC61BM-rich core and a P3HT-rich shell. For P3HT:ICBA nanoparticles, the particles are also core-shell in nature with a P3HT-rich shell and ICBA-rich core but upon annealing a highly intermixed P3HT:ICBA is formed, which is driven by the enhanced miscibility of ICBA in crystalline P3HT and this morphological change results in much higher device efficiencies.

▼ Core-shell nanoparticles have found increased attention in the past years due to their many potential applications in material science, i.e. catalysis, optics and biomedicine. In this thesis, well-defined silica nanoparticles (SNPs) coated with poly(2-methyl-2-oxazoline) (PMeOx) have been prepared and characterized for biomedical applications. SNPs were synthesized through the reverse microemulsion method followed by the chemical binding of PMeOx chains to the surface of the silica core via various approaches including “grafting to”, “grafting from”, and in-situ immobilization and polymerization of 2-methyl-2-oxazoline (MeOx). For the synthesis of PMeOx-coated SNPs via the “grafting to” approach, two different methods were employed involving click chemistry and the silane coupling reaction; however, only the latter method resulted in a relatively higher grafting density. The hybrid nanoparticle synthesis was further improved by fabricating the polymer shell via the “grafting from” approach and immobilization of an initiator on the particle surface before polymerization. Grafting density and thickness of the polymeric shell was controlled by varying the polymerization time and monomer/initiator ratio concentration. These hybrid nanoparticles were further functionalized with fluorescein isothiocyanate and folic acid as a fluorescence imaging molecule and cancer-targeting ligand, respectively. Moreover, hybrid nanoparticles with tris(bipyridine)ruthenium(II) chloride as a fluorophore encapsulated in the silica core were prepared before the PMeOx shell was formed by the “grafting-from” method. Finally, a novel one-pot method was designed and optimized entitled “in situ immobilization and polymerization of monomer” for the synthesis of PMeOx-coated SNPs. This led to a grafting density similar to the “grafting to” approach with the advantage of a simplified the reaction procedure.

▼ This thesis focuses on core/shell nanoparticle catalysts including preparation, characterization and testing performance using direct methanol fuel cell. Core/shell were prepared using noble and non-noble metals. Also some core/ shell nanoparticles supported on silica and different types of carbon were prepared as well in this thesis. Non-noble core/shell nanoparticles including novel Co/Ni, SiO2/Ni using three types of silica and novel SiO2/CoFe were prepared by a new modified sol-gel method using hydrazine in alkali media as the reducing agent to reduce metal chloride through two steps process. Parameters such as temperature, pH of solution and reducing agents, were seen to be of great importance in deciding the morphology of the final product as well as the structure of the core/shell catalyst. Core/shell nanoparticles have been successfully prepared for Co/Ni and SiO2/CoFe for first time by choosing the right parameters. This study presents the unique structure which has not been obtained previously for SiO2/Ni catalyst using commercial silica as core. A novel halo shaped structure was the common feature in the catalysts prepared as indicated by TEM. This study presents as well noble Ru/Pt core/shell nanoparticles supported on three types of carbon by a new modified polyol method for first time. The author of this work is not aware of any studies that have prepared Ru/Pt on carbon powder smaller or equal to 50 nm and Ru/Pt on CMWNT previously. This work presents special structure (crown- jewel shaped) for Ru/Pt on Vulcan XC-72 carbon which was not obtained previously for the same catalyst. Selected catalysts were tested using a direct methanol fuel cell. SiO2/Pt core/shell nanoparticles were prepared for the first time by two different methods, namely a new modified sol-gel and polyol methods with novelty structures halo and crown- jewel shaped respectively. Based on the particles size obtained from TEM images, the modified polyol method seems to have a much greater impact on the particles size than the modified sol-gel method. Based on these findings Ru/Pt, Ru/Pt supported on three different types of carbon and Pt supported on CMWNT were prepared using the new modified polyol method. Pt on CMWNT catalyst was synthesized for the first time successfully by a new modified polyol method and all the particles were found to be well dispersed with a narrow size distribution of an average particles size of 3nm. This catalyst gave promising results on DMFC. Pt supported on CMWNT and Ru/Pt supported on Vulcan and CMWNT were used for the first time as electro-catalysts in DMFC to study the effect of the support on the catalytic activity of catalysts. The results show that Ru/Pt on CMWNT gives better performance than the unsupported Ru/Pt and Ru/Pt on Vulcan XC-72. Using Ru/Pt on CMWNT with higher methanol concentration (anode feed) improved the fuel cell power density when compared with the RuPt commercial catalyst.

Nanoligas bimetálicas têm atraído a atenção de pesquisadores nas últimas décadas devido a possibilidade de ajustar suas propriedades físico-químicas, tais como propriedades elétricas, ópticas, magnéticas e de reatividade, por meio da variação do número de átomos, da composição química e do formato geométrico. As nanoligas bimetálicas que combinam Pt com outros metais são especificamente interessantes na área de catálise heterogênea, devido a possibilidade de se obter materiais com propriedades distintas de seus respectivos sistemas unários no que se refere ao surgimento ou aumento da atividade catalítica, à seletividade e, muitas vezes, ao preço reduzido. Esse trabalho tem como objetivo investigar as propriedades estruturais, energéticas, eletrônicas e de estabilidade de nanoligas bimetálicas core-shell de 55 átomos que combinam Pt com metais de transição (MT) pertencentes às séries de transição 3d, 4d e 5d dos grupos de Fe a Zn. Esses sistemas foram estudados utilizando cálculos de primeiros princípios (ab initio) baseados na teoria do funcional da densidade, tal como implementada no código computacional VASP (Vienna Ab initio Simulation Package). As nanoligas putativas de mínimo global energético (pGMC) de composição Pt13MT42 e Pt42MT13 calculadas nesse estudo apresentaram características particulares quanto à geometria e ao arranjo das espécies metálicas na nanoliga. Ao que diz respeito aos arranjos core-shell, foram observados dois arranjos em que a fica Pt no caroço (Pt13Ag42 e Pt13 Au42) e sete arranjos em que a Pt fica na superfície (Pt42Fe13, Pt42Co13, Pt42Ni13, Pt42Cu13, Pt42Ru13, Pt42Rh13 e Pt42Os13). Os mecanismos que levam à formação destas e das demais nanoligas pGMC foram investigados com base em três fatores: raio atômico, energia de superfície e cargas de Bader. Verificou-se que raio e a energia de superfície competem como fator determinante pelas posições preferenciais de cada espécie metálica na nanoliga. Nos casos em que houve divergência, o raio apresentou-se como o fator de maior importância, entretanto, quando o raio das espécies são muitos próximos, a energia de superfície exerce um papel de maior importância. A partir da análise de cargas de Bader, observou-se ocorrência de transferência de carga da região do caroço para a região da superfície para a maioria das nanoligas. No mais, observou-se que as nanoligas core-shell contam com atração coulômbica de maior magnitude do que as demais nanoligas pGMC, como resultado de altas cargas de sinal oposto em cada uma das regiões.

Bimetallic nanoalloys have been attracting attention since the last decades due to the possibility of adjusting their physical-chemical properties, such as electrical, optical, magnetic and reactivity properties, by means of the variation of the number of atoms, chemical composition and geometry.

▼ The limited capability of the traditional nuclear shell model in dealing with calculations for nuclei with large numbers of valence nucleons or with phenomena requiring multiple shells for their description motivated ongoing research on establishing an economical model space, one which still could reveal nuclear structural properties but in a lower dimensional space compared to the traditional shell model. Towards this goal, the generalized seniority shell model (GSSM) and the symplectic no-core shell model (Sp-NCSM) were developed. The GSSM is based on the BCS description of nucleon pairing. It is most effective for spherical and semimagic shell-configured nuclei. The Sp-NCSM is established on the SU(3) many-body basis motivated by the SU(3) symmetry structure of the harmonic oscillator many-nucleon basis states, embedded further with a higher Sp(3,R) symmetry, as an extension of SU(3) symmetry to multiple harmonic oscillator shells. We set up a recursive method to compute matrix elements in the GSSM basis. This method is implemented and carried out in a computer program we developed for nuclear calculations under the generalized seniority scheme. The GSSM was not previously well benchmarked, and we have used our method and code to test this model by comparing the calculated nuclear properties in the GSSM model space with calculations in the full shell model space. Such comparison is made under the same nucleon-nucleon interaction for both spaces. Meanwhile, the Sp-NCSM offers a different approach to modeling light nuclei without the need to assume the presence of an inert core. Numerical evidence shows an important role of the symplectic Sp(3,R) symmetry in the ab initio no-core shell model results for light nuclei. Therefore, the construction of Sp(3,R) states from SU(3) states is necessary, as a prerequisite and crucial step of understanding the symplectic symmetry for those nuclei. We contribute to the Sp-NCSM by providing the numerical calculation that decomposes the basis states of Sp(3,R) irreducible representations (irreps) in terms of the SU(3) nuclear basis.

▼ The literature review of proposed doctoral thesis summarizes knowledge of both present-day biomaterials and the new type of “smart” biomaterials such as thermosensitive copolymers. Among those copolymers whose aqueous solutions are liquid at laboratory temperature but turn into a solid gel as the temperature rises to 37 °C belong e.g. amphiphilic triblock copolymers based on the biodegradable hydrophobic polylactide, polyglycolide and hydrophilic poly(ethylene glycol) (PLGA PEG PLGA). Commercially available thermosensitive PLGA PEG PLGA copolymers, known as ReGel or OncoGel are used as injectable controlled drug delivery systems for diabetes or cancer treatment, respectively. However, PLGA PEG PLGA copolymers might be used as well as inorganic drug delivery carries and biodegradable implants for regenerative medicine in orthopedic and dental applications. For this reason the biocompatible hydroxyapatite (HAp), utilized in the bone remodeling process, was employed because of its majority representation in hard tissue. The experimental part of this work is focused on the preparation of HAp/PLGA PEG PLGA composites, where used HAp was in the form of either nano- (n-HAp) or core-shell (CS) particles. Novel core-shell particles, prepared by double emulsion method, were consisted of “rigid” n-HAp core covered by PLGA PEG PLGA shell additionally end-functionalized by itaconic acid (ITA/PLGA PEG PLGA/ITA). ITA modification brought crosslinkable both double bonds and functional carboxylic groups to the ends of copolymer chains. Consequently, the ITA/PLGA PEG PLGA/ITA copolymer shell was chemically crosslinked to form life-time controlled 3D polymer network surrounded HAp core resulting in crosslinked core-shell particles (CS-x). The ATR-FTIR spectroscopy proved the presence of “new” ester bonds in polymer shell at 1021 cm-1 arising from the carbodiamide coupling reaction between -OH and -COOH groups. As mentioned above, both n-HAp and CS-x particles were mixed with the copolymer thermosensitive PLGA PEG PLGA matrix and flow/gelation behavior important for injectable materials were evaluated by rheological measurement. . It was found, that the addition of less than 5 wt.% of n-HAp particles or 10 wt.% of CS-x particles into the PLGA PEG PLGA polymer matrix retains its thermosensitive properties. However, adding higher amount of either n-HAp particles or CS-x particles in copolymer matrix changed the aqueous sol to permanent stiff gel while the temperature increases above 37 °C. Based on the ICP-OES analysis, the release of CS-x particles from 10 w/v % PLGA PEG PLGA gel matrix to the incubation medium at 37 °C was faster than in case of n-HAp particles (6 % vs. 3% in 9 days, respectively) which are more strongly bonded to matrix micellar structure. As a conclusion, composite based on n-HAP particles in copolymer matrix exhibiting stiff permanent gel at body temperature is suitable more as biodegradable bone adhesive while composite consisting of CS-x particles in thermosensitive copolymer matrix is useful as… Advisors/Committee Members: Vojtová, Lucy (advisor), Kučerík, Jiří (referee), Lehocký,, Marián (referee).

Since the early 90's researchers have investigated the combination of nanocomposites comprised of multilayers, which have better efficiency than their corresponding individual particles, may present in certain cases, new properties. The resulting structure is called a core-shell. In this study, were synthesized ZrO2:Y 3+ coated with TiO2, obtaining nanocomposites ZrO2:Y 3+ @TiO2 with a thickness of 10, 20 and 50% shell. The photoluminescent property (FL) of the nanocomposites was studied. Such interest is due to the fact that the order/disorder structural at the interface of the core-shell type systems may be possible recombination processes responsible for the photoluminescence emission of these materials. Nanoparticles of the core and the shell were obtained by the Method of Polymeric Precursors. The samples were characterized by X-ray diffraction (XRD) to identify the formation of the nanocomposite and evaluate the structural order in the synthesized materials. The core was obtained with tetragonal structure and the shell with anatase structure. From the diffractograms have been carried out calculations of the crystallite size and lattice parameters. The characterization by Transmission Electron Microscopy (TEM), it was not possible to differentiate the core of the shell by the images, since both are structurally ordered, requiring analysis by Energy Dispersive X-ray (EDX), which was verified the presence of Zr and Ti elements that comprise the core-shell nanocomposite. The FL emission results were explained as a function of the shell thickness, as well as the effect of calcination temperature on the order-disorder structural material. To evaluate the performance of the FL issuing nanocomposites were calculated chromaticity coordinates, based on the FL emission spectra.

Desde o início da década de 90 pesquisadores vêm investigando a combinação de nanocompósitos constituídos por multicamadas, os quais apresentam melhor eficiência do que suas partículas individuais correspondentes, podendo apresentar em alguns casos, novas propriedades. A…

Among the various iron oxides studied, a magnetite (Fe3O4) stands out due to its superparamagnetic behavior and its high biocompatibility. Luminescent properties working cooperatively in magnetic nanoparticles with which the material converts certain types of energy into emission of electromagnetic radiation at the same time, which enables an interaction by magnetic fields. In the present work, an investigation and structural, elemental and morphological analysis of superparamagnetic / luminescent particles formed by coating of iron oxide by an SiO2 base network was carried out. The Fe3O4 oxide was synthesized by the coprecipitation method, and in the Eu3+ rare earth together with the 1,10-phenanthroline linker in the network, were responsible for energy transfer processes in systems that checked as optical materials for materials. The nanocomposites synthesized obeyed the formation of a core-shell system and was verified by micrographs obtained by Electron Transmission Electron Microscopy, evidencing a formation of nanoparticles of varied sizes. As the compositions of the phases of the materials were characterized by X-ray Diffraction, Radiated Spark Energy and Absorption Spectroscopy in the Infrared region, showing a crystal phase of the magnetic oxide and a formation of nanocomposite. The properties of interest (magnetism and photoluminescence) were evaluated and the respective results presented agreed with each other, with characteristic emissions of Eu3+ emitting a pink coloration, and an emission intensity for a concentration of this species in the material. The materials presented a superparamagnetic behavior, evidencing that the oxide coating did not change as Fe3O4 magnetic characteristics, and is in turn presented in a saturation magnetization of 55 emu / g with a magnetic domain of 8.9 nm. As nanoparticles have dimensions that indicate that a part has a magnetic domain.

Entre os diversos óxidos de ferro estudados, a magnetita (Fe3O4) destaca-se, devido ao seu comportamento superparamagnético e a sua alta…

A reação de redução de oxigênio (RRO) foi estudada em eletrocatalisadores com estruturas do tipo core-shell formadas por monocamadas de Pt depositadas sobre nanopartículas a base de Au e Pd, e estruturas hollow formadas de Pt. As nanopartículas core-shell foram sintetizadas por deposição em regime de subtensão utilizando-se substratos de Au e Pd. As estruturas hollow foram preparadas a partir de nanopartículas core-shell de Pt sobre Ni ou Co, seguido por ciclagem eletroquímica em eletrólito ácido. Os eletrocatalisadores foram caracterizados utilizando-se as técnicas de Energia Dispersiva, Difração e Espectroscopia de Absorção de Raios X e Microscopia Eletrônica de Transmissão. Os testes eletroquímicos foram feitos voltametria cíclica e curvas de polarização em eletrodo rotatório. Os catalisadores do tipo core-shell mostraram uma alta atividade para a RRO, o que foi associado a mudanças nas propriedades eletrônicas e geométricas da Pt, causadas pela presença dos átomos de Au e Pd, que conduzem a uma menor força de adsorção Pt-O. Neste caso, temos um melhor balanço de reatividade para as tendências opostas de quebra e formação de ligações nos intermediários reacionais adsorvidos na superficie do eletrocatalisador. As nanopartículas de Pt hollow apresentaram maior atividade que o electrocalisador de Pt/C. Isto foi atribuído aos fenômenos de contração da rede cristalina e abaixamento do centro de banda d da Pt devido à ligação da Pt com Ni ou Co remanescente na partícula. Estas estruturas mostraram que é possível o desenvolvimento de eletrocalisadores com baixa carga de platina, mas com atividade superior ao do material no estado-da-arte de Pt/C, através de modificações na estrutura e composição da nanopartícula.

The oxygen reduction reaction (ORR) was studied on eletrocatalysts with core-shell structures formed by Pt monolayers deposited on Au and Pd, and by hollow strutures of Pt. The core-shell nanoparticles were synthesized by the Under Potention Deposition technique, using Au and Pd as substrates. The hollow structures were prepared starting foram core-shell nanoparticles of Pt deposited on Ni or Co, followed by electrochemical cycling in acid media. The eletrocatalysts were characterized using techniques of X Ray Diffration, Energy Dispersive X Ray Spectroscopy, X Ray Absorpion Spectroscopy, and Transmission Electron Microscopy. The electrochemical tests were cyclic voltammetry, and polarization curves with rotating disk electrode. The core-shell electrocatalysts howed high activity for the ORR, this increase being associated with changes in the geometric and electronic properties of Pt, caused by the presence of Au and Pd atoms, leading to a lower adsorpion strength of Pt-O. This effect conducts to a better balance of reactivity for the two opposing tendencies of breaking and bond formation in the reaction intermediates adsorbed on the catalyst surface. The Pt hollow nanoparticles showed higher activity in relation to that of Pt/C, which was attributed to the effects of contraction of the Pt lattice and…
