| Abstract: | The poly(2, 5 dimethoxyaniline) film electrodes (Pt PDMA/Pt) dispersed platinum microparticles were prepared by electrochemical method.The electrodes which combine electroactivity and catalytic activity exhibit a higher electrocatlytic activity for oxidation of formaldehyde in aqueous solution of 0 5mol/L H 2SO 4.The catalytic activity depends on the size,distribution and amount of the loaded platinum microparticles,as well as on the concentration of formaldehyde and the temperature of electrocatalytic oxidation. |

| Keywords: | electro catalysis poly(2 5 dimethoxyaniline) platinum micro particles formaldehyde cyclic voltammetry |
