Abstract

Here, we report a facile approach for synthesizing M–N–C catalysts (M = Co, Fe, Ni) at a commercial scale without employing organic solvents. Our characterization efforts indicate that single atomic catalysts with high surface areas were successfully obtained. Electrochemical measurements demonstrate that, among the three synthesized catalysts, Ni–N–C exhibits the highest performance in the electrochemical CO₂ reduction reaction (CO₂RR) to carbon monoxide (CO), affording 80% Faradaic efficiency (FE) of CO production at –0.49 V_RHE with a turnover frequency (TOF) of 57,379 h^–1. Large-scale synthesis coupled with high performance allows moving forward with the practical implementation of M–N–C catalysts for industrially relevant CO₂RR.
