Abstract: The production of high value-added chemicals through electrocatalytic carbon dioxide reduction (CO2RR) utilizingrenewable electricity represents an innovative approach for converting renewable energy into chemical energy, which can be storedin fuels. This method not only facilitates the transformation of electricity into chemical energy but also promotes the resourcefulutilization of CO2. Such technological pathways address the challenges associated with the storage of renewable energy andsignificantly contribute to the achievement of the "dual carbon goals". From a techno-economic perspective, carbon monoxide (CO)emerges as one of the most promising products for industrialization among the various outputs of CO2RR. Recent advancements inelectrocatalytic technology have led to remarkable progress in the conversion of CO2 to CO via electrocatalytic reduction. Thedevelopment and application of diverse catalysts have been pivotal in driving breakthroughs in this field. This paper reviews therecent research progress pertaining to catalysts used for CO2 conversion through electrocatalytic reduction. It provides an overview ofthe current status of noble metal catalysts, single-atom catalysts, and molecular catalysts highlighting their respective advantagesand disadvantages. Furthermore, the paper offers insights into future development directions in this area.
