390	O desenvolvimento de nanopartículas de intermetálicos ordenados de ouro e estudo da atividade eletroquímica da reação de oxidação do glicerol / Barrezzi, Karina. January 2015 (has links) Orientador: Antonio Carlos Dias Ângelo / Banca: Dayse Iara dos Santos / Banca: Joelma Perez / Resumo: No presente trabalho foram estudadas as reações de oxidação do glicerol, em meio alcalino (KOH), sobre a superfície dos materiais Au/C, AuSn/C e Au2Bi/C, sintetizados por microemulsão, e AuSn/C e Au2Bi/C, sintetizados por redução por poliol. A caracterização física dos materiais foi realizada por DRX e EDX. Pelos difratogramas obtidos, foi verificado que, através do método da microemulsão, ligas AuSn/C e Au2Bi/C foram formadas, e que pelo método de redução por poliol ocorreu formação de cluster, constituído por Au e Sn, e de um material formado pela liga Au2Bi/C e por Bi. A liga AuSn/C não apresentoyu variação significativa na composição atômica obtida por EDX em relação a razão atômica nominal, indicando que o método de microemulsão foi eficiente na preparação desse material. Já o cluster, apesar de ter tido reprodutividade nos diferentes pontos analisados, não apresentou a composição atômica esperada. Em relação aos materiais formados por Bi, estes não mostraram coerência nos resultados obtidos por EDX. A caracterização eletroquímica da superfície foi realizada por voltametria cíclica. O desempenho eletroquímico dos materiais frente ao processo eletro-oxidação do glicerol foi avaliado tanto por voltametria como por cronoamperometria. Todos os materiais apresentaram desempenho eletroquímico, porém a liga AuSn/C foi a que apresentou os melhores resultados devido a um efeito eletrônico e um possível efeito bifuncional / Abstract: In the present work, we studied the oxidation reaction of glycerol, in alkaline medium (KOH), on the surface of Au/C, AuSn/C e Au2Bi/C materials, synthesized by microemulsion, and Au/Sn/C and Au2Bi/C, by reduction of polyol. The physical characterization of materials was performed by XRD and EDX. By diffractograms obtained it was found that, by the microemulsion method, AuSn/C and Au2Bi/C alloys have been formed, and by the polyol reduction method, occurred cluster formation consisting of Au and Sn, and a material formed by the Au2Bi/C alloy and Bi. The AuSn/C alloy showed no significant variation in the atomic composition obtained by EDX in relation to the nominal atomic ratio, indicating that the microemulsion method was effective in preparing this material. However, the cluster, despite having reproducibility from various points analyzed did not show the expected atomic composition. In relation to the materials formed by Bi, these showed no coherence in the results obtained by EDX. The electrochemical characterization of the surface was accomplished by cyclic voltammetry. The electrochemical performance of the material against glycerol electrooxidation was assessed both by voltammetry and by chronoamperometry. All materials presented electrochemical performance, but the AuSn/C showed the best results, probality due to an electronic effect, and a possible bifunctional effect / Mestre Nanopartículas. Ouro.
