Progress in Perovskite-Type Catalysts Used in Selective Catalytic Reduction Denitrification
In the context of promoting the'double carbon'goal,people's environmental protection concept continues to progress,and the importance of pollution prevention and control as well as energy conservation and consumption reduction is increasing.Selective catalytic reduction(SCR),which has high denitration efficiency and good application value,is the focus of research in the field of denitration.In this paper,the research progress of perovskite catalysts used in SCR technology in recent years is reviewed.The characteristics of perovskite catalysts are analyzed,the ABO3,supported and doped perovskite catalysts are introduced respectively,and the common preparation methods of perovskite denitrification catalysts are summarized.Finally,the application of perovskite catalysts in SCR technology is summarized and prospected.
