多层聚吡咯-铂复合膜电极的甲醇电催化氧化
Electrooxidation of Methanol on Multilayer Films of Polypyrrole-Platinum Electrode
摘要
Abstract
Multilayer films of polypyrrole-platinum electrode were fabricated by cyclic voltammetric technique.Electro-oxidation of methanol on this electrode was investigated with the aid of cyclic voltammetry and chrono-amperometry. Results demonstrated that the multilayer of polypyrrole-platinum electrode behaved better electro-catalytic performance for electro-oxidaton of methanol and better poison resistant. Furthermore, with the increase of deposited platinum loadings, the rate controlling step on electro-oxidation reaction of methanol was changed from CO oxidation to sorption-desorption of hydrogen.关键词
