No. of bitstreams: 0 / No presente trabalho, o desempenho elétrico dos eletrocatalisadores anódicos Pt/C, Pt3Sn/C(liga), Pt(SnO2)/C, Pt3(SnO2)/C e Pt9(SnO2)/C para as reações de eletro-oxidação de etanol, acetaldeído e ácido acético foi investigado. Testes em célula unitária mostraram que a adição de Sn seja na forma de liga Pt-Sn ou na forma de óxido (SnO2) coexistente com a platina metálica aumenta consideravelmente a resposta elétrica gerada pela célula. A melhora no desempenho elétrico dos catalisadores a base de PtSn é resultado da capacidade em oxidar o acetaldeído, majoritariamente produzido pelo Pt/C, em ácido acético. Pt3(SnO2)/C exibiu a melhor resposta elétrica tanto para o etanol quanto para acetaldeído como combustíveis, alcançando valores de densidade de potência máxima de 127 e 58 mW cm-2, respectivamente. Misturas entre os combustíveis mostraram que o acetaldeído é um composto que leva a uma rápida desativação dos catalisadores, enquanto que o ácido acético, embora não seja oxidado a CO2 nas condições de operação, não afeta o desempenho elétrico da célula. / Dissertação (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Guest Intercalation Into Metal Halide Inorganic-Organic Layered Perovskite Hybrid Solids And Hydrothermal Synthesis Of Tin Oxide Spheres

Bandara, Nilantha 13 December 2008 (has links)
The work presented in this thesis is divided into two research areas. In part I, the synthesis and guest intercalation of inorganic-organic metal halide ammonium layered perovskites is discussed. Comparisons are made between the solid matrix before and after the intercalations, and all solids are characterized using thermogravimetric analysis (TGA) and powder X-ray diffraction (XRD). In part II, “templateree” hydrothermal synthesis of tin oxide spheres in the presence of different ortho-substituted anilines is discussed. The aim is to determine whether there are differences in the structures, shapes and surface morphology of the tin oxide spheres that correspond to the identity/shape of the ortho-substituent on the anilines. Solids were characterized by XRD, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) techniques.
