Efficient Electrooxidation of 5‐Hydroxymethylfurfural Using Co‐Doped Ni 3 S 2 Catalyst: Promising for H 2 Production under Industrial‐Level Current Density

Abstract Replacing oxygen evolution reaction (OER) by electrooxidations of organic compounds has been considered as a promising approach to enhance the energy conversion efficiency of the electrolytic water splitting proces. Developing efficient electrocatalysts with low potentials and high current densities is crucial for the large‐scale productions of H 2 and other value‐added chemicals. Herein, non‐noble metal electrocatalysts Co‐doped Ni 3 S 2 self‐supported on a Ni foam (NF) substrate are prepared and used as catalysts for 5‐hydroxymethylfurfural (HMF) oxidation reaction (HMFOR) under alkaline aqueous conditions. For HMFOR, the Co 0.4 NiS@NF electode achieves an extremely low onset potential of 0.9 V…
