Looking towards the economical and efficient carbon dioxide (CO2) utilization, metal-CO2batteries uphold a great potential to enhance the efficiency of CO2conversion to fuels. Pertaining to this, we have fabricated B, N-containing carbon with tubular morphology (C-BN@600) derived from ionic liquid (IL) and metal-organic framework (MOF) composite as cathode catalyst with Zn foil anode for aqueous rechargeable Zn-CO2battery. The C-BN@600 catalyst demonstrate a remarkable activity towards electrochemical CO2reduction to methanol with a Faradaic efficiency of 74% and a Yield rate of 2665μgh-1mg-1cat.. The assembled battery consumes CO2continuously and electrochemically convert it to methanol during discharge and simultaneously produces electrical energy with a remarkable energy density of 330Whkg-1and a power density of 5.42mWcm-2which is stable for more than 12 days (>300h, 800 cycles) at 1mAcm-2, providing a platform to serve a dual purpose of CO2reduction and energy storage. |
