利用热分解法制备了不同CeO2 含量的Ti基RuO2 CeO2 SnO2 涂层阳极 ,通过循环伏安曲线和电化学阻抗谱测试了所制备的涂层阳极的电催化性能 ,并用扫描电镜对涂层阳极的表面形貌进行了观察。结果表明 :制备温度对涂层阳极的性能有很大影响 ,在涂层阳极中引入CeO2 可以增加RuO2 CeO2 SnO2 涂层的有效活性表面积 ,从而提高涂层阳极的电催化活性 ,且CeO2 含量的最佳摩尔分数为 0 .4。
The Ti-based RuO2 CeO2 SnO2 coated anodes with different CeO2 contents were prepared by thermal decomposition. The electrocatalytic properties of the prepared coated anodes were tested by cyclic voltammetry and electrochemical impedance spectroscopy. Surface morphology was observed. The results show that the preparation temperature has a great influence on the performance of the coating anode. The introduction of CeO2 into the coating anode can increase the active surface area of the RuO2 CeO2 SnO2 coating and improve the electrocatalytic activity of the coating anode. Good mole score is 0.4.
