Abstract

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
