The isotopic effect on the electrochemical CO2 reduction reaction (CO2RR) is investigated in this study. Here, a higher CO2RR selectivity over its competing hydrogen evolution reaction was observed in D2O-based electrolytes compared with the H2O-based counterparts, which can be attributed to the lower [D+] concentration than [H+].
