RECYCLE-CO2 focuses on the electrochemical reduction of CO2 (CO2RR) into valuable chemicals and fuels using innovative and selective electrocatalysts. CO2RR, although being very promising, confronts many challenges due to the low energy content in CO2, high reaction energy barriers, slow kinetics for CO2 electroreduction, and low selectivity toward a specific product. Therefore, the design and development of highly active and selective catalysts is crucial for practical application of electrocatalytic CO2RR.
