摘要
氮氧化物(NO_x)对臭氧层会产生严重破坏,同时又是PM_(2.5)的重要前体物,NO_x在大气、水体和土壤中会产生严重污染。开发对NO_x的有效控制和降解技术对大气污染防治意义深远。本文对氮氧化物的危害和处理方法进行了讨论,阐述了纳米二氧化钛光催化技术在降解NO_x方面的应用,对纳米材料作为催化剂高效降解和去除氮氧化物的研究进行了展望。
Nitrogen oxide(NOx)will cause serious damage to the ozone layer,and it is also an important precursor of PM2.5.NOx will cause serious pollution in the atmosphere,water and soil.The development of effective control and degradation technology for NOx is of far-reaching significance for the prevention and control of air pollution.In this paper,the hazards and treatment methods of nitrogen oxides were discussed,and the application of nano titanium dioxide photocatalytic technology in the degradation of NOx was expounded.The research of nano materials as catalyst for high efficiency degradation and removal of nitrogen oxides was prospected.
