Electrochemical reduction of carbon monoxide has recently emerged as a potential approach for obtaining high-value products. Recent studies have shown that carbon monoxide can be electrochemically reduced to C₂₊ at high reaction rates, high selectivity, and inherently improved stability compared with carbon dioxide, highlighting the attractive potential of the electrocatalytic carbon monoxide reduction reaction (CORR). This review introduces recent progress in CORR mechanistic understanding and representative strategies for the design of copper-based electrocatalysts, such as alloying and doping, single-atom catalysts, crystal facet and morphology design, and oxide-derived copper. Several critical factors that influence the CORR activity and selectivity are also discussed, including pH, electrolytes, and the design of electrolysis reactors. Finally, the challenges and perspectives for further development in this field are summarized.
