Hydrogen production through electrochemical water splitting is a promising approach for sustainable energy generation, yet developing efficient and durable electrocatalysts remains critical challenge. This study successfully developed highly active platinum nanoparticles-decorated stainless-steel mesh (Pt/SSM) electrocatalyst the hydrogen evolution reaction (HER) using electrodeposition. The Pt nanoparticles exhibited unique micro-leaf structure on SSM surface. Pt/SSM demonstrated superior HER performance compared to bare SSM, with remarkably low overpotential of 121 mV Tafel slope 40 dec −1 in 0.5 M H 2 SO 4 . was their activity KOH, attributed higher proton concentration, favorable Volmer kinetics, improved catalyst-electrolyte interactions acidic medium. electrodeposited also more stable electrolytes alkaline ones, likely due preservation its morphological integrity conditions. Overall, this work practical production, medium providing optimal performance.
