铂修饰聚苯胺-聚硫堇复合电极对甲醇的电催化氧化
Electrocatalytic Performance of Platinum-modified PAni/PTn Composite Electrode toward Methanol Oxidation
摘要
Abstract
Thionine and aniline were polymerized electrochemically at graphite electrode,and Pt particles were deposited by electrochemical method,then Pt/PAni-PTn/graphite electrode was obtained. The morphology of Pt/PAni-PTn/graphite electrode was characterized by scanning electron microscope (SEM). SEM result shows that Pt particles are dispersed homogeneously on PAni-PTn composite film. The electrocatalytic activity of Pt/PAni-PTn/graphite electrode toward methanol electrooxidation was investigated by cyclic voltammetry (CV) and chronoamperometry (CA). Experimental results show that PAni-PTn as a catalyst support is better for Pt to improve its dispersion and reduce its size,showing larger active surface area. Pt/PAni-PTn/graphite electrode exhibits better electrocatalytic activity and long-term stability than Pt/graphite electrode.关键词
