Abstract The electrochemical reduction of carbon dioxide offers a sound and economically viable technology for the electrification and decarbonization of the chemical and fuel industries. In this technology, an electrocatalytic material and renewable energy‐generated electricity drive the conversion of carbon dioxide into high‐value chemicals and carbon‐neutral fuels. Over the past few years, single‐atom catalysts have been intensively studied as they could provide near‐unity atom utilization and unique catalytic performance. Single‐atom catalysts have become one of the state‐of‐the‐art catalyst materials for the electrochemical reduction of carbon dioxide into carbon monoxide. However, it remains a challenge for single‐atom catalysts to facilitate the efficient conversion of carbon dioxide into products beyond carbon monoxide. In this review, we summarize and present important findings and critical insights from studies on the electrochemical carbon dioxide reduction reaction into hydrocarbons and oxygenates using single‐atom catalysts. It is hoped that this review gives a thorough recapitulation and analysis of the science behind the catalysis of carbon dioxide into more reduced products through single‐atom catalysts so that it can be a guide for future research and development on catalysts with industry‐ready performance for the electrochemical reduction of carbon dioxide into high‐value chemicals and carbon‐neutral fuels.
