| 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.

| Abstract: | 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 used as analytical sensor in the measurement of the organic compounds. |
