The article focuses on the development of an efficient W/NiBP electrocatalyst for industrial-scale hydrogen generation through water electrolysis. The catalyst was synthesized using a hydrothermal approach followed by annealing, resulting in ultra-low overpotentials of 23 mV for the hydrogen evolution reaction (HER) and 215 mV for the oxygen evolution reaction (OER) at 20 mA/cm2 in 1 M KOH solution. It showed superior performance at high current densities (>500 mA/cm2) and operated at industrial-level current densities up to 2000 mA/cm2, outperforming Pt/C || RuO2 configurations. The electrode maintained excellent stability under harsh industrial electrolysis conditions for 7 days. The catalytic activity of the W/NiBP electrocatalyst was also observed in natural water, acidic, and neutral solutions, attributed to W-induced active sites and synergistic element contributions. The combination of nickel, boron, and phosphorus in NiBP provided a strong base material for effective water splitting. The introduction of tungsten (W) atoms enhanced electrochemical conductivity and structural robustness, accelerating the catalytic activity. Overall, the study highlights the potential of the W/NiBP electrocatalyst for efficient and sustainable hydrogen generation, addressing the challenges of high current density operation and long-term stability in industrial electrolysis applications.
