The recent advances in carbon-supported single-atom catalysts (SACs) for electrochemical reactions are comprehensively reviewed. The development and advantages of carbon-supported SACs are briefly introduced, followed by a detailed summary of the synthesis strategies employed for various carbon-supported SACs, including vapor phase transport, high temperature pyrolysis,and wet chemical methods. Subsequently, the advanced characterization techniques for carbon-supported SACs are reviewed. The applications of carbon-supported SACs in diverse fields, such as oxygen reduction reaction, carbon dioxide reduction reaction, nitrogen reduction reaction, hydrogen evolution reaction, and oxygen evolution reaction are summarized. Special emphasis is given to the modification strategies enabling carbon-supported SACs to exhibit excellent electrocatalytic performance. Finally, the prospects and challenges associated with utilizing carbon-supported SACs for electrochemical reactions are discussed.
