Converting CO into valuable products via photo-, electro-, and photoelectrocatalysis offers the possibility of simultaneously mitigating global warming and energy shortages. Single-atom catalysts (SACs) have garnered significant interest from researchers owing to their optimal atom use, suitable coordination environments, distinctive electronic structures, and highly dispersed active sites. This work offers a thorough examination of the progress of research on SACs for photocatalytic, electrocatalytic, and photoelectrocatalytic conversion of carbon dioxide. The fundamental concepts of photo-, electro-, and photoelectrocatalytic reduction of CO are briefly described, respectively. Second, the preparation approaches and characterization techniques of SACs are summarized, with a focus on how to increase the single-atom loading rate and achieve scale-up preparation. Finally, the specific applications of SACs for photo-, electro-, and photoelectrocatalytic conversion of CO are discussed, and the future development of SACs in the field of CO catalytic reduction is summarized and prospected. Herein, the aim is to provide guidance and insights for the systematic design of SACs used in CO reduction reactions, serving as a reference for the further advancement of photo-, electro-, and photoelectrocatalytic reduction of CO.
