摘要
以电位扫描法将铂微粒沉积在聚２，５┐二甲氧基苯胺薄膜电极上制得铂微粒掺杂的聚２，５┐二甲氧基苯胺电极．该电极集催化活性和电活性于一体，在甲醛浓度为１ｍｏｌ／Ｌ的硫酸溶液里的电化学氧化显示了较高的催化活性．铂微粒的大小、分布和载量，甲醛的浓度。
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.
