Fund Project:

poly(2,5-dimethoxyaniline) film electrodes were prepared by electrochemical method. Metallic platinum microparticles were dispersed into poly(2,5-dimethoxyaniline) matrix by cyclic voltammetry. The electrocatalytic activity of the film electrode was studied for electrooxidation of methanol in protonic acid. It is shown that the incorporation of platinum microparticles into the polymer matrix results in a further ten-fold increase in activity as compared with naked platinum electrodes.The preparation temperature of poly(2,5-dimethoxyaniline) film has a pronounced influence on the electrochemical behaviour. Some important factors which affect electrochemical reactions were discussed.
- platinum microparticle,
- poly(dimethoxyaniline),
- methanol,
- electrocatalytic oxidation
