摘要:

Electrochemical reduction of CO2 to carbon-containing fuels possesses the potential to solve the environment issues caused by excess CO2 in the atmosphere. Herein, we introduce a ternary Au-CDots-C3N4 electrocatalyst for efficiently reducing CO2 to CO. The ternary catalyst exhibited significantly enhanced activity and stability for CO2 electroreduction compared with pure AuNPs. The Au-CDots-C3N4 electrocatalyst demonstrates a high CO FE of ~79.8% at -0.5V, and a 2.8-fold enhancement of current density (with the Au loading only 4 wt%) at -1.0V relative to pure Au NPs. The DFT calculations and experimental observations indicate that the high activity towards CO2RR originates from the synergetic effect between Au NPs, CDots and C3Nsubstrate, and the capability of Hand CO2 adsorption from CDots. The long-term stability tests demonstrate the electrocatalyst can be used for over 8 hours without obvious deactivations and maintained its activity over 60 days under normal condition.
