Sustainable water electrolysis has emerged as a future technology for producing green hydrogen. The general approach to improving water-splitting hydrogen production is develop novel electrode materials. In this work, we reported an orthogonal approach, namely, regulating the electrolyte components. As proof of concept, Na2S additive was introduced electrolytes enhance performance Ni-based electrodes. Specifically, tiny amount (50 mM) employed reduce evolution overpotential Ni(OH)2 from 262 193 mV at 10 mA cm-2. situ Raman studies unveiled formation NiS active phase and S-H bond during electrocatalysis, which were responsible such improvement. Moreover, strategy also showed its success in other materials metallic Ni foam, saline water, catalytic reaction systems oxygen evolution.
