摘　　要：采用热解氧化与电沉积的方法制备了钛基SnO2和PbO2电极,并通过SEM进行了表征.以甲基橙为目标有机物,采用循环伏安、线性伏安等手段考察了甲基橙在不同电极上的电催化氧化行为.研究结果表明,甲基橙在电极上均可被直接氧化,所制电极具有较强的电催化活性.SnO2 and PbO2 electrodes on Ti substrates were produced by thermo-decomposition and eletrodeposition respectively. The surface morphology of the electrodes was characterized by SEM. Taking methyl orange as model substrate,the electro-catalytic oxidation of it on different electrodes was studied by cyclic voltammetry and liner voltammetry. The results showed that methyl orange can be oxidated directly, and the electrodes take on good electro-catalytic characteristics.
