The article discusses the synthesis and evaluation of Ni-V porous cathode materials for enhancing the catalytic activity of the hydrogen evolution reaction (HER). By doping vanadium into Ni2V intermetallic compounds, the electronic structure is modulated, leading to improved hetero-phase interfacial adsorption sites. The study focuses on different cathode compositions, including three-phase structures, pure Ni2V phase, and dual-phase Ni2V/V. Electrochemical experiments confirm the superior performance of the Ni2V/V hetero-phase interface in HER catalysis, showing high stability under high currents in alkaline electrolytes. The introduction of vanadium optimizes adsorption sites and enhances capacities for water and hydrogen adsorption on Ni2V. The research provides valuable insights into designing cost-effective cathode materials for alkaline hydrogen production and offers a blueprint for industrial-scale electrolytic catalysts. The fabrication of porous Ni-V cathodes via powder metallurgy techniques is highlighted as a cost-efficient method for enhancing HER performance. Overall, the study contributes to the development of efficient and low-cost materials for sustainable hydrogen production.
