摘要
研究了钛铁试剂催化电合成的聚吡咯膜电极(PPE/Pt)在水溶液中对抗坏血酸(AH_2)的电催化氧化反应.循环伏安结果表明,AH_2在PPE/Pt电极上的氧化峰电位负移超过400多mV.讨论了pH值,扫描速度和膜的厚度对催化性能的影响.
The electrocatalysis oxidation reaction of the catalitic electrochemically synthesized polypyrrole film to the ascorbic acid in aqueous solution is studied. The cyclic voltammograms indicate that the oxidative peak potential of ascorbic acid on the polypyrrole film electrode shift more than 400 mV to the minus. The effects of the value of pH, scan rate and thickness of the film on the catalysis are also discussed.
