Abstract (en)
[origin: WO2021122323A1] Electrochemical conversion of CO2 to formic acid or a salt thereof, using an indium containing catalytic electrode, comprising (a) electrochemically converting CO2 to formic acid or a salt thereof by applying a voltage to an electrochemical cell comprising the catalytic electrode as cathode and an anode, wherein the electrochemical cell is fed with an electrolyte comprising CO2; and (b) regenerating the catalytic electrode by lowering the voltage and subsequently washing the catalytic electrode with an aqueous liquid and exposing the catalytic electrode to air without applying voltage; and (c) optionally repeating steps (a) and (b).
