Abstract
"ELETROCATALISADORES CONTENDO NANOPARTìCULAS METáLICAS A BASE DE PLATINA-ESTANHO SUPORTADAS EM CARBONO PARA USO COMO áNODO NA OXIDAçãO DIRETA DE áLCOOIS EM CéLULAS A COMBUSTìVEL COM MEMBRANA TROCADORA DE PRóTONS". A presente patente de invenção refere-se a utilização de eletrocatalisadores contendo nanopartículas metálicas, a base de platina-estanho e contendo ainda um ou mais elementos (Ti, Zr, V, Nb, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Cu, Ag, Au, Zn, Ga, Bi, U e elementos da série dos lantanídeos), suportadas em carbono de alta área superfícial como ânodo na oxidação direta de álcoois, especialmente etanol, em células a combustível com membrana trocadora de prótons (do inglês Proton exchange Membrane Fuel Cell - PEMFC).
