摘要:

采用热压-电镀法制得PbO2-固体高聚物电解质(SPE)组合电极. 通过伏安曲线和槽压与过电位曲线的测量, 研究羟基新戊醛在该组合电极上电氧化行为. 通过PbO2-SPE组合电极在阳极液中有、 无液相支持电解质及不同阴极液情况下的循环伏安曲线和线性伏安曲线比较, 证明该组合电极对羟基新戊醛氧化有较好的电催化作用.

Abstract:

The lead dioxide-solid polymer electrolyte(SPE) membrane composite electrode was prepared by hot-press and electroplating methods. The electrooxidation behavior of hydroxypivalaldehyde was studied by means of cyclic voltammetric and cell voltage-overpotential curves. The current response  at the PbO2-SPE composite electrode and cell voltage were analyzed with or without liquid supporting electrolyte in the anolytes as well as in different catholytes. It was found from the experiment restuts that the PbO2-SPE composite electrode had a good electrocatalytic activity for the  oxidation of hydroxypivalaldehyde.

Key words: PbO2-SPE composite electrode; Solid polymer electrolyte; Hydroxypivalaldehyde;  Electrooxidation
