摘要
光电催化技术是一种以电化学法作为辅助的光催化氧化技术。特别对难以降解的废水中有机物具有强大的催化功效,是21世纪研究有机废水降解的发展方向之一,具有广阔的发展空间。综述了光电催化技术的主要机理、半导体光电极的种类及其对几种典型有机污染物的降解效果,展望了光电催化废水处理技术的发展前景。
Photoelectrocatalysis technology is a kind of photocatalytic oxidation technology assisted with electrochemical method.It has specially powerful catalysis efficiency in degrading the organic matter in waste water.It is a developmental direction of study organic waste water degradation in 21st century,and has broad developmental space too.The main mechanism of photoelectrocatalysis technology,the kinds of semiconductor photoelectrode and the effect of photoelectrocatalysis on the degradation of some typical organic pollutants are reviewed.Moreover,the tendency of future prospective technology development are indicated in this paper.
