摘　　要：半导体光催化在环境保护和未来新能源开发等领域中具有重要的作用和意义.由于参与光催化反应的主体是光生载流子,并涉及光生电子和空穴的界面转移与复合,(光)电化学方法是研究光催化反应微观动力学和机理的重要手段.本文主要介绍作者课题组应用这类研究方法在液相光催化去污方面所获得的部分研究结果,并对今后研究重点提出了某些看法.Semiconductor photocatalysis plays a critical role in the environment protection and future energy development. （Photo）electrochemical measurements are powerful tools for studying the kinetics and mechanism of photocatalytic reactions, since photo-carriers, as reactants of photocatalytic reactions, are involved in the interfacial transfer and recombination of semiconduc- tor/electrolyte interface. This review describes the part of our recent results regarding aqueous photocatalytic decontamination ob- tained by these methods, and the focus of future work in this field is suggested.
