【中文摘要】 利用旋转圆盘电极对纳米PbO2修饰电极的电催化氧化性能进行了初步的研究.实验表明由于电极表面PbO2晶粒呈纳米结构,使纳米PbO2修饰电极表面具有大的比表面积,高的表面活性中心,良好的导电性及宏观隧道效应,使得纳米PbO2修饰电极对苯酚有很好的氧化催化性能,用安培法测定了多种有机物在纳米PbO2修饰电极上的电流响应,实验表明,纳米PbO2修饰电极可以作为分析传感器用于有机化合物的测定中. 【英文摘要】 The preliminary electrocatalytic oxidation property of nano PbO_2 modified electrode by using rotating disk electrode was discussed. It was demonstrated that the nano PbO_2 modified electrode had a large specific area, a high surface active center, a good conductivity and macro tunnel effect because of its nanostructure, and therefore it had a very good catalytic and oxidizing property to the organic compounds. So the current response of many organic compounds on the nano PbO_2 modified electrode can be ...
