Abstract
A method of electrochemical reduction of CO2 includes the use of a catalyst of Cu/Cu2O particles including Cu/Cu2O interfaces. The catalyst may be included in an electrochemical cell for the conversion of CO2 to value-added products. The electrochemical cell may include an anode, a cathode including the Cu/Cu2O particles including Cu/Cu2O interfaces, and an aqueous medium containing CO2 or CO3−2. The CO2 or CO3−2 is reduced by contacting the Cu/Cu2O particles with the aqueous medium while supplying electricity to the cell. The conversion of CO2 by the electrochemical reduction thereof has higher Faradaic Efficiency due to the Cu/Cu2O interfaces in the Cu/Cu2O particles.
