Abstract

Highlights Electrodes with NiMoO₄ nanosheet arrays were fabricated by rapid laser scanning over nickel foam in a precursor solution. The LIHR method significantly increased the production rate 19 times faster, using only 27.78% of the energy compared to conventional hydrothermal methods. The integrated electrode IE-NiMo-LR exhibits superior hydrogen evolution reaction performance, requiring low overpotentials to achieve high current densities and maintaining stability over 350 h. The IE-NiMo-LR/IE-NiFe-L pair efficiently splits water, needing only 1.55 V to reach 100 mA·cm⁻² in 1 M KOH electrolyte.
