Study on the Performance of Electrochemical Degradation with Ti/TinO2n-1 Electrode

  • 摘要: 采用SEM、EDS对钛基亚氧化钛电极进行形貌和成分表征,用线性极化曲线法和循环伏安法测试电化学性能,通过降解模拟污水测试降解性能以及用荧光光谱法检测自由基。结果表明,钛基亚氧化钛电极上不能发生直接氧化反应,但是电极析氧电位可达2.18 V(vs.SCE),并且检测到生成大量·OH,是一种类似于Ti/SnO2的惰性电极,在NaCl和Na2SO4电解质溶液中电流效率分别达40.95%和22.52%,降解效果优于Ti/SnO2和Ti/RuIr电极。
    Abstract: In order to study the mechanism and performance of electrochemical degradation of sewage Ti/TinO2n-1 electrode,the morphology and component were characterized by SEM and EDS,the electrochemical performance was tested by linear polarization curve and cyclic voltammetry,fluorescence spectroscopy was used to detect hydroxyl radicals and the performance of sewage degradation was tested through electrochemical degradating simulation sewage.The result shows that oxidation reaction can not occur directly on Ti/TinO2n-1(4 ≤ n ≤ 10) electrode,however,its overpotential of oxygen evolution can be up to 2.18V(vs.SCE).It was detected that it can produce large amount of hydroxyl radical,indicating that it is a non-active electrode,similar to Ti/SnO2 electrode.Also it shows that the current efficiency can be up to 40.95% and 22.52% in Na Cl and Na2SO4 electrolyte solutions respectively.The degradation efficiency of Ti/TinO2n-1is superior to that of Ti/SnO2 and Ti/RuIr electrodes.
