钒基脱硝催化剂的研究进展

Research Progress of Vanadium-based Denitrification Catalyst

氮氧化物(NOx)是大气主要污染物之一,其排放会带来严重的环境问题并且威胁人类健康,所以控制其排放势在必行。选择性催化还原脱硝已经成为世界上最成熟的脱硝技术。本文主要从催化剂的制备方法出发,详细综述不同方法制备的钒基脱硝催化剂的研究现状,并对脱硝机理进行表述,最后对钒基脱硝催化剂的发展进行总结和展望。

Nitrogen oxide(NOx)is one of the main pollutants in the atmosphere,the emission of NOx can cause serious environmental problems to threaten human health,it is imperative to control its emission.Selective catalytic reduction has become the most mature denitrification technology in the world.In this paper,the research status of vanadium-based denitrification catalyst was reviewed according to diverse preparation methods,and mechanism of denitrification was described.Finally,the development of vanadium-based denitrification catalyst was summarized and prospected.
