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 electrocatalytic oxidation of ascorbic acid (AH_2) in aqueous solution was studied by means of electrospinning of polypyrrole membrane electrode (PPE / Pt) catalyzed by ferrotitanium reagent. The cyclic voltammetry results showed that the oxidation peak potential of AH_2 at PPE / Pt electrode was negative Shifted over 400 mV.The effects of pH, scan rate and membrane thickness on the catalytic performance were discussed.
