Mn-based catalysts have attracted significant attention in the field of catalytic research, particularly in NO catalytic reductions and CO catalytic oxidation, owing to their good catalytic activity at low temperatures. In this review, we summarize the recent progress of Mn-based catalysts for the removal of NO and CO. The effects of crystallinity, valence states, morphology, and active component dispersion on the catalytic performance of Mn-based catalysts are thoroughly reviewed. This review delves into the reaction mechanisms of Mn-based catalysts for NO reduction, CO oxidation, and the simultaneous removal of NO and CO. Finally, according to the catalytic performance of Mn-based catalysts and the challenges faced, a possible perspective and direction for Mn-based catalysts for abating NO and CO is proposed. And we expect that this review can serve as a reference for the catalytic treatment of NO and CO in future studies and applications.
