Hydrogen energy represents a novel source characterized by its diverse range of origins, high density, and absence carbon emissions. Coupled hydrogen evolution (CHE) is to achieve efficient, energy-saving, economical generation constructing systems that promote synergistic interactions between multiple reaction steps in order reduce consumption optimize resource utilization. This study reports the design preparation vanadium(V)-doped Ni3S2 (V-Ni3S2@NF) electrocatalyst on nickel foam substrate. The electrocatalytic material exhibits excellent electrochemical performance when catalyzing glycerol oxidation (GOR) (HER). Specifically, electrode only needs apply voltage equivalent reversible potential (RHE) 1.41 0.56 V driving current intensity GOR HER 100 mA cm–2. In addition, 0.15 V-Ni3S2@NF stability characteristics under continuous operation conditions for 10 h. conclusion, was employed as bifunctional material, comprehensive analysis context synergistically enhancing conducted. For conversion formate, Faradaic efficiency (FE) consistently remains at level over 85%. Similarly, system, FE production approximately 99%. findings suggest significant selectivity during processes HER, few side reactions occur consume electrical energy.
