Ammonia selective catalytic reduction of nitrogen oxides (NOx) technology with V2O5-WO3 (MoO3) / TiO2 as the core catalyst is currently widely used. But it has many problems such as narrow and high temperature window, easy to poison by alkali inactivation, vanadium"s biological toxicity and secondary pollution to the environment, which require researchers to develop new efficient and environmentally friendly catalyst systems. Due to its unique structure, perovskite materials have good mid-high temperature activity, excellent high temperature resistance, sintering resistance and environmental protection and harmless characteristics, which has attracted more and more concerns in the field of selective catalytic reduction of NOx. This paper summarized the research progress of perovskite NH3-SCR catalysts in recent years. The main types of perovskite catalysts, denitration activity, structure-activity relationship and reaction mechanism were comprehensively discussed. The future possible development direction of perovskite NH3-SCR catalysts are prospected.
