Self-supported Ni/NiO heterostructures with a controlled reduction protocol for enhanced industrial alkaline hydrogen evolution† Self-supported Ni/NiO heterostructures with controllable ratios used in industrial alkaline water electrolysis (AWE) systems lead to an ultralow voltage of 1.79 V at 400 mA cm−2 for 2 weeks, ascribed to the synergic combination of abundant active sites, rapid electron/mass transfer and optimal HER kinetics.

Hydrogen has been recognized as a green energy carrier, which can relieve energy shortage and environmental pollution. Currently, alkaline water electrolysis (AWE) driven by renewable energy to produce large-scale green hydrogen is a mainstream technology. However, tardy cathodic hydrogen evolution reaction (HER) and stability issue of catalysts make it challenging to meet the industrial requirements.
