光电催化材料在降解有机污染物中的研究进展∗

摘要

Photoelectrocatalysis photocatalytic reaction technology is an electrochemical assisted by applying an external bias to reduce photo-generated electrons and holes in the compound, thereby improving the quantum efficiency, and resulting in a complete mineralization of the organic contaminants. An overview of the development process photoelectrocatalysis technology based on photocatalytic technology was summarized. Besides, the recent development and application of new photoelectric catalytic material for waste water treatment were also reviewed.%光电催化是一种电化学辅助的光催化氧化技术，通过施加偏置电压减少光生电子和空穴的复合进而提高其量子效率，使有机污染物彻底矿化。本文以光催化技术为基础，概述了光电催化技术的发展历程和光电催化氧化技术机理，并基于光电催化技术中存在的光电极光电转换效率较低，光电催化活性不高等问题，综述了近年来新型光电催化材料的发展与应用，并展望了光电催化水处理技术的发展前景。
