Abstract
Abstract Copper is the only metal that can convert CO 2 into C2 and C2+ in electrocatalytic carbon dioxide reduction (CO 2 RR). However, the Faraday efficiency of CO 2 conversion to C2 and C2+ products at high current densities is still low, which cannot meet the actual industrial demand. Here, the design methods of single‐atom copper catalysts (including regulating the coordination environment of single‐atom copper, modifying the carbon base surface and constructing diatomic Cu catalysts) are reviewed, and the current limitations and future research directions of copper‐based single‐atom catalysts are proposed, providing directions for the industrial conversion of CO 2 into C2 and C2+ products.
