光催化降解是解决环境问题的一种绿色技术。阐述了光催化降解有机污染物的基本原理、提高光催化剂活性的途径。重点介绍了光催化材料在环境中有机污染物处理中的应用,分析了光催化材料发展中存在的问题,并展望了光催化材料的未来发展方向。
Photoeatalytic degradation is a green technology for solving environmental pollution problems. A discussion was made of the photocatalytie reaction mechanism in this paper. And a summa- ry was made of the ways to improve the photocatalytie activity in details. The authors focus on introduc- ing the research progress of photoeatalyst in processing environment organic pollutants. An analysis was made of some problems existing in the progress of photocatalytic materials with the future research visualized.
