| 摘 要： | 研究了电化学聚合制备的聚乙撑二氧噻吩(PEDOT)膜修饰电极对对苯二酚和邻苯二酚的电催化.结果表明PEDOT膜修饰电极对对苯二酚和邻苯二酚均有很强的电催化作用,它们可能来自PEDOT对二羟基酚类的吸附作用.研究和分析了影响膜催化性能的2个因素:聚合电位、掺杂离子.PEDOT膜中掺杂的阴离子对催化性能有重要的影响,而膜聚合电位对PEDOT膜修饰电极行为的影响则是由于膜电阻随膜聚合电位的变化所引起的.

| Abstract: | The electrode processes of catechol and p -dihydroxybenzene on Pt electrode modified with PEDOT membrane are investigated. The PEDOT film/Pt electrode has very strong electrocatalytic ability for both of electrode processes. Two factors affecting the electrocatalytic behavior of PEDOT/Pt electrode, the polymerization potential and different doping anions, are studied and discussed. The experiments and preliminary analysis show that PEDOT electrocatalysis for catechol and p -dihydroxybenzene may come from the adsorption of dihydroxybenzene on PEDOT film and the doping anions play an important role in the electrocatalysis. The effect of polymerization potential is resulted in voltage drop of the resistance of PEDOT film. |
