大气中的氮氧化物(NO_x,包括NO和NO_2)是二次气溶胶形成的重要前体物之一,对我国雾霾形成具有重要贡献,因此氮氧化物的污染控制迫在眉睫。纳米光催化是近年发展起来的一门新兴交叉学科,凭借其绿色、高效、低能耗等特点,在环境治理领域展现出广阔的应用前景,尤其为低浓度环境大气污染物深度治理开拓了新思路。中国科学院地球环境研究所环境污染控制团队在NO_x的光催化降解方面取得新进展。在前期半导体纳米
Nitrogen oxides (NO x, including NO and NO 2) in the atmosphere are one of the important precursors for the formation of secondary aerosol, which is an important contribution to the formation of haze in our country. Therefore, the control of nitrogen oxides pollution is imminent. Nano-photocatalysis is a newly emerging interdisciplinary developed in recent years. Due to its characteristics of greenness, high efficiency and low energy consumption, nano-photocatalysis has shown broad application prospects in the field of environmental management. In particular, it has opened up new ideas for the depth control of air pollutants in low-concentration environments . Environmental Pollution Control Team, Institute of Earth Environment, Chinese Academy of Sciences made new progress in the photocatalytic degradation of NO_x. In the early semiconductor nano
