摘　　要：针对低温氨选择性催化还原(NH_(3)-SCR)催化剂易因烟气中水蒸气和SO_(2)中毒的问题,从制备方法、载体类型、结构形貌调控3个方面综述了提高低温NH_(3)-SCR催化剂抗水抗硫性能的方法,深入探讨了催化剂结构形貌与其抗水抗硫性能之间的关系,详细介绍了低温NH_(3)-SCR催化剂设计和制备的新思路,并指出,今后应加强低温NH_(3)-SCR催化剂结构和形貌调控方面的研究。Aiming at the problem of catalyst poisoning in low-temperature with selective catalytic reduction with ammonia(NH_(3)-SCR)by H2O and SO_(2)in flue gas,this article reviews the methods for improving the water-and sulfurresistance of low-temperature NH_(3)-SCR catalysts from three aspects:preparation methods,carrier types,and structure and morphology control,deeply explores the relationship between the structural and morphology of catalysts and their water-and sulfur-resistance performance,and introduces new ideas for the design and preparation of low-temperature NH_(3)-SCR catalysts in details.It is pointed out that research on the structure and morphology control of low-temperature NH_(3)-SCR catalysts should be strengthened in the future.
