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 showsthat 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 forPt to improve its dispersion and reduce its size,showing larger active surfacearea.Pt/PAni-PTn/graphite electrode exhibits better electrocatalytic activityand long-term stability than Pt/graphite electrode.

Key words: Pt, polyaniline, polythionine, methanol, electrocatalytic oxidation
