Abstract (en)
[origin: WO2022148856A1] A self-cleaning CO2 reduction strategy is proposed herein including alternating operation and regeneration of the CO2 electrolysis system. The strategy includes application of short and periodic reductions in applied voltage, thereby avoiding saturation and prevention of carbonate salt formation.
