The direct electro-reduction of diluted CO2 in acidic media can circumvent CO2 purification and reduce carbon loss. Here, the authors use an ionomer coating layer to enrich the diluted CO2 and block proton transport, thereby achieving high carbon utilization in diluted CO2 in an acidic electrolyte.
