有毒难降解有机污染物的光催化降解

Photocatalytic Degradation of Persistent and Toxic Organic Pollutants

有毒难降解有机污染物的光催化降解在原理、过程和效率等方面仍然存在着巨大的挑战,特别是光催化剂的构效关系、可见光的利用、分子氧的活化和污染物分子矿化分解的机理仍然是今后的研究热点.本文就近年来在半导体光催化和负载型铁离子光催化降解有毒有机污染物的两个重要方面的研究进展进行了评述.

Studies on photocatalytic degradation of toxic and non-biodegradable organic pollutants remain a great challenge in principles, processes, and efficiencies. The main attention has been focused on the relationship between structure and efficiencies, the utilization of visible light, and the mechanisms for dioxygen activation and pollutants decomposition and/or mineralization of pollutants. Recent advances in the photocatalytic degradation by TiO2 and supported iron complexes were discussed in this review.
