摘要
High surface area niobium-doped titanium oxide catalyst supports were synthesized through a chemical method using nano-sized polystyrene (PS) latex as a template By varying the concentration of template with respect to mania and niobium precursors we were able to produce niobium-doped titanium oxides with surface areas of 75-115 m(2)/g and sufficient electrical conductance to function as fuel cell catalyst supports The oxides were subsequently platinized and evaluated as oxygen reduction catalysts using a rotating disk electrode One of the samp
