Converting CO into value-added products by photocatalysis, electrocatalysis, and photoelectrocatalysis is a promising method to alleviate the global environmental problems and energy crisis. Among the semiconductor materials applied in CO catalytic reduction, Cu O has the advantages of abundant reserves, low price and environmental friendliness. Moreover, Cu O has unique adsorption and activation properties for CO , which is conducive to the generation of C products through CC coupling. This review introduces the basic principles of CO reduction and summarizes the pathways for the generation of C , C , and C products. The factors affecting CO reduction performance are further discussed from the perspective of the reaction environment, medium, and novel reactor design.
