Research Progress of Catalysts in CO Oxidation

This paper mainly discusses the catalysts used for CO catalytic oxidation, from three aspects: metal oxide catalysts, noble metal catalysts and single-atom catalysts. Metal oxide catalysts have a certain catalytic activity for CO oxidation, but the catalytic activity is low; compared with metal oxide catalysts, noble metal catalysts have better catalytic activity, but the metal utilization rate is low, resulting in waste of resources. The emergence of single-atom catalysts effectively solves the above problems and provides a basis for the efficient CO oxidation reaction.
