A review of carbon-supported single-atom catalysts for electrochemical reactions
Recent advances in the use of carbon-supported single-atom catalysts(SACs)for electrochemical reactions are com-prehensively reviewed.The development and advantages of carbon-supported SACs are briefly introduced,followed by a detailed summary of the synthesis strategies used,including vapor phase transport,high temperature pyrolysis and wet chemical methods.Ad-vanced characterization techniques for carbon-supported SACs are also reviewed.The use of carbon-supported SACs in different fields,such as the oxygen reduction reaction,carbon dioxide reduction reaction,nitrogen reduction reaction,hydrogen evolution re-action,and oxygen evolution reaction are summarized.Special emphasis is given to the modification strategies used to enable car-bon-supported SACs to have an excellent electrocatalytic performance.Finally,the prospects and challenges associated with using carbon-supported SACs for electrochemical reactions are discussed.
