Abstract

Abstract : Operando XAS reveals that the copper catalysts undergo a remarkable reduction to the metallic state during CO2 RR. Abstract : We have developed a flow cell for the operando X-ray absorption spectroscopy of CO2 RR, providing an identical catalytic environment as that of the electrochemical measurement. Two model catalysts, metallic copper and copper hydroxide, are investigated. These catalysts undergo a remarkable reduction to the metallic state in the flow cell during CO2 RR.
