摘 要: 利用熱分解法制備了不同CeO2含量的Ti基RuO2-CeO2-SnO2涂層陽極， 通過循環(huán)伏安曲線和電化學(xué)阻抗譜測試了所制備的涂層陽極的電催化性能， 并用掃描電鏡對涂層陽極的表面形貌進(jìn)行了觀察。結(jié)果表明： 制備溫度對涂層陽極的性能有很大影響， 在涂層陽極中引入CeO2可以增加RuO2-CeO2- SnO2涂層的有效活性表面積， 從而提高涂層陽極的電催化活性， 且CeO2含量的最佳摩爾分?jǐn)?shù)為0.4。

Abstract:Titanium based RuO2-CeO2-SnO2 coating anodes with various CeO2 content were prepared by thermal decomposition. The electrocatalytic activity of coating anodes was studied by cyclic voltammetry test and alternation current impedance test. The morphology of coating anode was studied by scanning electron microscopy (SEM). Results show that the sintering temperature influences electrocatalytic properties of coating anode, the electrocatalytic properties of coating anode are improved by doping with CeO2, and CeO2 content of 0.4(mole fraction) is adaptive. The reason of improving the electrocatalytic proprties is that CeO2 composition increases the activity surface area of coating anode.
