Abstract:

Photoelectrocatalysis water treatment is a kind of photocatalytic oxidation technologies assisted with electrochemical method.Photogenerated electrons can be removed from electrodes before they could recombine with the holes by the application of a suitable external bias potential,so the quantum efficiencies can be improved and the organic pollutants mineralized completely.The principle and mechanism of photoelectrocatalysis,and the influencing factor of photoelectrocatalysis on the degradation of a few typical organic pollutants are reviewed.Moreover,the tendency of future prospective technology development and some research topics in this aspect are also indicated.

Key words: photoelectrocatalysis, photocatalyticoxidation, wastewatertreatment

摘要:

光电催化水处理是一种电化学辅助的光催化反应技术,通过施加外部偏压减少光生电子和空穴的复合,从而提高其量子效率使有机污染物彻底矿化。作者综述了光电催化的机理、光电催化反应的影响因素及光电催化氧化技术对几种典型有机污染物的降解情况,展望了光电催化水处理技术的发展前景,并提出了需进一步完善的研究内容。
