N2 - Facile synthesis of hierarchically functional, catalytically active, and electrochemically stable nanostructures holds tremendous promise for catalyzing efficient and durable oxygen evolution reaction (OER), yet remains a formidable challenge. Herein, we report the scalable production of core-shell nanostructures comprised of carbon-coated cobalt diphosphide nanosheets, C@CoP2, via three simple steps: (i) electrochemical deposition of Co-species; (ii) gas phase phosphidation, and (iii) carbonization of CoP2 for catalytic durability enhancement. Electrochemical characterizations showed that C@CoP2 delivers an overpotential of 234 mV, retains its initial activity for over 80 hours of continuous operation, and exhibits a fast OER rate of 63.8 mV dec-1 in base.
