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/SnO_2的惰性电极,在Na Cl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/SnO_2和Ti/Ru Ir电极。
SEM and EDS were used to characterize the morphology and composition of titanium-based titania electrodes. The electrochemical performance was tested by linear polarization curve and cyclic voltammetry. The degradability was tested by degradation of simulated wastewater and the free radicals were detected by fluorescence spectroscopy. The results showed that the direct oxidation reaction could not occur on titanium-based titania electrode, but the potential of oxygen evolution was up to 2.18 V (vs.SCE) and a large amount of OH was detected. It was an inert electrode similar to Ti / SnO_2 , The current efficiency of NaCl and Na2SO4 electrolyte solutions were 40.95% and 22.52% respectively, and the degradation efficiency was better than that of Ti / SnO_2 and Ti / Ru Ir electrodes.
