摘要: 用电化学方法制备的载有金属铂微粒的聚苯胺(PAn)膜电极对甲醇在硫酸中的电化学氧化具有很高的催化活性。电极材料中的铂微粒是沿着聚苯胺的纤维分布的,而且主要沉积在PAn膜的表面。

Abstract: The polyaniline film electrodes with platinum microparticles were prepared by electrochemical method. The morphology of the electrode was examined by scanning electron microscopy. Oxidation of methanol in 0.5mol/L H2SO4 indicated that the platinum microparticles were dispersed in a three-dimensional array in polyaniline film,mainly loaded on the surface of polyaniline film. A very high electrocatalytic activity in oxidation of methanol in 0.5mol/L H2SO4 was found.The catalytic current was much higher than that obtained on the bare platinum and polyaniline film electrode.

Key words: methanol, electrocatalytic oxidation, polyaniline, platinum microparticle
