Advances in the understanding of selective CO2 reduction catalysis

Year: 2024

Type: article

Abstract: The electrochemical synthesis for value‐added chemicals and fuels via carbon dioxide reduction reaction (CO2RR) offers an effective route to close the anthropogenic carbon cycle and store renewable energy. Currently, the copper‐based catalyst is still the only choice for generating various CO2RR species beyond two electron products. However, the wide range of CO2RR products generated on copper leads to low selectivity, and their low concentrations in electrolytes pose great costs in the downstream purification process and significantly challenge the scalability of this technology. To make this technology economically viable, enhancing product selectivity is crucial. In this review, we identify the primary CO2RR species and discuss the latest insights into the reaction mechanisms controlling CO2RR selectivity. Then, we examined factors that affect CO2RR selectivity. Emphasizing these factors in catalyst design, we highlight the importance of advanced technologies to expand our knowledge and prospects for the future of the CO2RR.
