Abstract:

Optically transparent electrode (OTE) coated with nanostructured thin TiO₂ films was made, which is used as the working electrode and catalyst. The method of electrochemical assisting photocatalysis degradation of the dyes in aqueous solution is studied.

Key words: photocatalyst, photoelectrocatalyst, dye, electrochemistry

摘要：

作者制备了纳米结构TiO₂ 膜及光透电极，并以此作为工作电极和光催化剂，研究了光电催化方法对水溶液中染料的降解效果。分析了温度、初始浓度、外加偏压等工艺因素对光电催化降解的影响。并进行了光降解和光催化降解方法的对比试验。同光致分解、光催化降解相比，光电催化降解对三种染料一品红、铬蓝K、铬黑T 溶液的降解效果最好。
