Randomized trial develops high-activity, low-cost hydrogen evolution catalysts, suggesting an alternative to noble metals.

This research aims to develop efficient and cost-effective hydrogen evolution catalysts based on nickel to replace noble metal catalysts.
Composite catalyst based on Ni, Ni(OH)2, and NiO prepared via multi-field coupled electrodeposition.
Hydrogen evolution performance evaluated under alkaline conditions using reversible hydrogen electrode.
Durability tests conducted at current densities of 1000 mA·cm−2.
Achieved low overpotentials of 248 mV at 500 mA·cm−2 and 341 mV at 1000 mA·cm−2.
Demonstrated long-term stable operation with maintained microstructure at high current densities.
Theoretical calculations indicated enhanced adsorption capacity and optimized ion transport in the new catalyst design.
