Waste denitration catalyst is a typical refractory muti-metal hazardous waste from the energy industry, and its annual emission reaches 500,000 m3 in China. Therefore, the efficient disposal of waste SCR denitrification catalysts and the recycling of valuable elements in waste SCR denitrification catalysts have become the focus of current research. In this review, we introduced the properties of waste SCR denitrification catalysts, summarized the research progress of disposal methods and resource recovery of waste SCR denitrification catalysts in recent years, and compared the advantages and disadvantages of each method. Finally, the efficient recovery and utilization of waste SCR denitrification catalysts were prospected.
