摘要/Abstract

摘要： 应用循环伏安法电沉积多层聚吡咯-铂复合膜电极,研究该电极的甲醇电催化氧化性能.循环伏安和计时安培法测试表明,该复合膜电极具有更好的甲醇电催化活性和抗毒性.铂量增加,电极反应控制步骤将由CO氧化转化为甲醇的吸附脱氢.

关键词: 甲醇氧化, 电化学催化, 聚吡咯, 循环伏安, 电沉积

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 chronoamperometry.Results demonstrated that the multilayer of polypyrrole-platinum electrode behaved better electrocatalytic 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.

Key words: methanol electro-oxidation, electrocatalysis, polypyrrole, cyclic voltammetry, electrodepositon
