Energy‐Saving Electrochemical Hydrogen Production via Amorphous CoMoP/NF Bifunctional Catalyst Coupled with HMF Oxidation Reactions in Alkaline Electrolyte

To improve water splitting efficiency and enhance energy utilization, it is crucial to develop catalysts with excellent activity, long‐term stability, and low cost. In this study, we synthesized a three‐dimensional nanostructured amorphous CoMoP/NF bifunctional catalyst for both the hydrogen evolution reaction (HER) and the 5‐hydroxymethylfurfural oxidation reaction (HMFOR), using a sacrificial template method. Benefiting from element doping regulation and morphology control, CoMoP/NF exhibited outstanding catalytic activity. Notably, in an electrolytic water system coupled with HER and HMFOR, a cell voltage of only 1.5 V was required at a current density of 20 mA cm−2, approximately 189 mV lower than that of a traditional water electrolysis system. This study presents a novel energy‐saving method for hydrogen production through the HER/HMFOR electrolysis system.
