摘要

氮氧化物是空气污染物中的主要成分,目前通过以V₂O₅为主的催化剂进行选择性催化还原来控制烟气中氮氧化物的排放,该催化剂具有脱硝效率高、适用范围广的特点,但是低温活性低、运行能耗高。二氧化钛(TiO₂)光催化选择性还原技术是一种可在中低温下将氮氧化物转化为氮气的绿色方法,具有广阔的应用前景。综述了TiO₂光催化技术在还原氮氧化物领域的现状及发展动态,以及增强TiO₂光催化材料体系光催化效率的途径,并对目前光催化选择性还原氮氧化物技术的研究方向提出了可行性建议。

Abstract

Nitrogen oxides (NO_x) are the main components of air pollutants.Selective catalytic reduction method is wildly applied to control the nitrogen oxides (NO_x) emission in flue gas with V₂O₅ own to high denitrification and wide usage.But it also has the disadvantages of low low-temperature activity and high energy consumption.Photo-catalytic selective reduction of NO_x is an environmentally friendly treatment process for purifying flue gas with TiO₂,which utilizes light to convert NO_x into N₂ under middle and low temperature.The advantages of high low-temperature activity and low energy consumption make it have broad application prospects.The recent advances in photo-catalytic reduction of NO_x and the ways improve the efficiency were reviewed.And some suggestions on the current development direction of photo-catalytic selective reduction NO_x technology were put forward.

Key words： TiO₂; air pollution; photo-catalytic selective reduction; nitrogen oxide
