摘要： 将以铂微粒修饰玻碳电极(GC)为基体的聚2,5-二甲氧基苯胺膜(PDMA)形成修饰电极(Pt/PDMA/GC).循环伏安实验表明,Pt/PDMA/GC电极对甲醇氧化比分散于玻碳电极上的铂催化活性更大。讨论了PDMA膜厚度、铂微粒含量及甲醇浓度对催化活性的影响。这种电极在酸性甲醇溶液中具有良好的稳定性。

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.
