氮氧化物去除技术中催化剂的研究进展

选择性催化还原法（SCR）是燃煤电厂等工业领域中去除高浓度氮氧化物最有效的技术，而光催化（Photocatalytic）方法则为最具潜力的去除城市空气环境中低浓度氮氧化物的技术。概述了选择性催化还原中各种金属、非金属以及多孔材料的沸石催化剂的发展及不足，介绍了光催化技术催化原理并就催化剂的选择、制备影响因素进行了综述和评价。最后，对SCR催化剂和光催化剂的发展进行了展望。

Progress Research on the Catalysts in the Removal of NOX Technologies

SCR had been a most efficiently technology of remove high concentration NOX in a industry field,and Photocatalytic was a most potential technology of remove dilute NOX for air environmental of city.This paper reviewed the development and deficiency of diversified catalysts in SCR.The catalytic principle of photocatalysis technology,selective catalysts were introduced and impact factor of preparing were reviewed and evaluated.Otherwise the future development of these two methods were presented.
