With the continuous implementation of the"double carbon"policy and the continuous improvement of people's awareness of environmental protection,carbon monoxide(CO),as a typical air pollutant,has become the main control object of industrial and automobile exhaust emissions.Noble metal catalysts for CO oxidation are one of the most effective means for CO catalytic oxidation treatment due to their excellent low-temperature activity,anti poisoning and anti-corrosion properties.Based on the research status of noble metal type CO oxi-dation catalysts,this paper focuses on the noble metal regulation technology and carrier controllable technology of Pt,Pd,Au,Ag and Rh noble metal catalysts,summarizes the performance optimization ways and develop-ment directions of noble metal type CO oxidation catalysts,and provides guidance for the development of better performance CO oxidation catalysts.
