Abstract

An efficient carbon-based catalyst is designed for enhancing the anodic carbon oxidation reaction (COR), replacing sluggish oxygen evolution to enable hydrogen production below the 1.23 V boundary potential of water electrolysis, realizing low energy consumption of 3.53 kW h m−3 H2. Pyridinic-N optimizes hydroxy group adsorption on adjacent carbons, boosting the COR efficiency.
