抄録

Electrocatalytic oxidation of methanol on Pt modified polyaniline electrodes was investigated with the aim of developing highly active composite electrodes for direct methanol fuel cells. Cyclic voltammetry and chronoamperometry were used to evaluate the catalytic activity in sulfuric acid solutions containing methanol. Pt / polyaniline modified carbon electrodes showed higher catalytic activity towards oxidation of methanol than Pt deposited carbon electrodes. The effect of different protonic acids used in the electrochemical preparation of polyaniline on the oxidation current of methanol was studied. Largest oxidation current was obtained for polyanilines prepared in sulfuric acid solutions.
