摘　　要：V2O5/AC催化剂是当前低温SCR烟气脱硝催化剂的研究热点,结合国内外对脱硝机理以及抗中毒能力方面存在的问题。综述了AC性质以及V2O5负载量对催化剂的影响,重点分析了对脱硝机理和催化剂中毒机理,指出了NH4HSO4是催化剂失活的关键物质,分析其在催化剂表面的反应行为,并为以后的研究提供方向。V2O5/AC catalyst is a research focus of low temperature SCR flue gas de-NOx in recent years, scientists did a lot of research work for its de-NOx activity and resistance to-poisoning ability. It does the carding for the research about V2O5/AC catalyst, comment on the influence of the nature of AC and the loading amount of V2O5 on the catalyst, highlight display the understanding, of the mechanism of de-NOx and catalyst poisoning, point out the NH4HSO4 is the key substance in the deactivation of catalyst, and analyses the reaction behavior on the surface of catalyst, and offer the direction for future research.
