A highly efficient atomic nickel catalyst for CO2 electroreduction in acidic electrolyte

Abstract

The development of single atom catalysts (SACs) for CO2 electroreduction in acidic electrolytes can greatly improve the CO2 utilization efficiency but remains challenging. We report a carbon-embedded atomic nickel catalyst prepared from carbon black, porphyrin and nickel(II) salts. The catalyst shows excellent activity for CO2 reduction with high CO faradaic efficiency of 99.9% and an industrial-level CO partial current density of 296.4 mA cm−2 in acidic media, which indicates the importance of carbon-supported SACs.
