摘要
目前.空气中有机污染物的健康危害及降解为人关注,纳米材料光催化反应在降解空气中的有机污染物方面取得了良好的效果。笔者阐述了光催化降解有机物的基本原理,并比较不同有机物降解效果。简要描述了纳米 TiO_2的应用,同时初步探讨了影响催化反应的因素以及提高催化效率的方法。
The organic pollutants in the air is so harmful to human health and is difficult to be degraded. However, to degrade the organic pollutants with nano-matefials by photocatalysis reaction can get a good effect. The basic principle of photocatalysis reaction of the nano-materials was explained and the different degradation effects for organic pollutants were compared in this paper. The application of nanosize TiO2 was briefly described and meanwhile the affecting factors and the methods to improve the catalysis efficiency were discussed.
