摘要
本文论述可用两种方法将同多钼酸催化剂固定在导电聚吡咯薄膜电极上,从而制得具有表面功能的同多钼酸-聚吡咯薄膜修饰电极,该修饰电极保持了同多钼酸的电化学活性和电催化性能,并具有良好的稳定性,对酸性水溶液中的氯酸钾具有较好的电催化还原作用,催化过程为EC平行催化机理。
This work shows that isopolymolybdic acid catalyst can be fixed on the conducting polypyrrole film electrode bY one-step and two-step methods, and the isopolymolybdic acid-polypyrrole film modified electrodes with surface function have been prepared. This modified electrode maintains the electrochemical and electrocatalytic properties of isopolymolybdic acid, and has good stability and catalytic activity on the reduction of chlorate ions in acidic aqueous solution. The catalytic process is an EC catalytic mechanism
