Abstract At present, developing low temperature, high activity, high stability and low cost catalysts is the key research direction of CO-SCR technology. This paper mainly introduces the catalytic reduction mechanism of CO-SCR technology, and reviews the research progress of CO-SCR catalysts at home and abroad in recent years, starting with noble metal catalysts and transition metal oxides catalysts. Numerous studies have shown that CO-SCR catalysts still have many limitations. To achieve large-scale industrial applications, further theoretical calculations need to be combined to improve the antioxidant performance of the catalyst, and the detailed influence paths of factors such as H2O, SO2, and alkali metals in CO-SCR reactions need to be analyzed.
