Abstract

Abstract: The poly(2,5-dimethoxyaniline)(PDMA)film electrode(Pt/PDMA/GC)with platinum microparticles was prepared by electrochemical method.The cyclic voltammograms indicate that the oxidative peak current of methanol at the Pt/PDMA/GCelectrode increases obviously than bare Pt electrode.The effects of the thickness of PDMAfilm, the quantity of platinum microparticles, the concentration of methanol and time on the catalysis are also discussed. The electrode exhibited an excellent and a long-term stability in the acidic methnaol solutions.

Key words: Electrocatalysis, Poly(2,5-dimethoxyaniline), Methanol, Platinum microparticles, Cyclic voltammetry
