Abstract The production of hydrogen from seawater offers a potential pathway to accomplish sustainable energy solutions. However, this process is impeded by the sluggish kinetics evolution reaction (HER) and corrosive nature seawater. In work, an FeRu alloy electrocatalyst integrated with Mo substrate (FeRu/MoO 2 @Mo) developed, specifically designed for HER in both alkaline environments. FeRu/MoO @Mo catalyst demonstrated remarkable performance, achieving overpotentials only 22, 42, 65 mV solution, simulated seawater, real at 10 mA cm −2 . Moreover, exhibited long‐term stability HER, maintaining its activity least 400 h under conditions 1 m KOH. situ Raman spectroscopy theoretical calculations revealed incorporation Fe reduces density states near Fermi level Ru, thereby optimizing adsorption–desorption behavior enhancing activity. This work scalable cost‐effective strategy development efficient non‐platinum catalysts.
