Ammonia selective catalytic reduction of nitrogen oxides (NOx) technology with V2O5-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 their unique structure,good stability and environmentally friendly characteristics,perovskite materials have become a research hotspot in the field of selective catalytic reduction of NOx. We reviewd the research progress of perovskite NH3-SCR catalysts at home and abroad in recent years,and comprehensively discussed the main types,denitrification activity and structure-activity relationship of perovskite catalysts. At the same time,the research progress of perovskite in the new field of photo photo-assisted SCR technology was introduced. In addition,we summarized the research on the NH3-SCR reaction mechanism of perovskite catalysts,and prospectd the possible future development directions and research goals of this field.
