چکیده

Surface modification is a promising approach to modulate the electrocatalyst properties for their further use in energy storage and conversion. In this work, electrochemical-based was proposed generate metallic particles-supported graphite rod (GR). The based on cathodic activation of GR presence alkali metal salts dry organic solvent. activated possess high reducing power that successfully employed spontaneously reduce aqueous media. surface analyses confirm formation nanoparticles supported GR. Interestingly, were found be generated onto intercalated into Next, materials used as drive hydrogen evolution reaction. Our results demonstrate electrocatalytic performances depend various parameters including radius cation injected charge during electrochemical activation. as-prepared Pt/Li-GR exhibits best activity stability toward necessary overpotential value reach current density 10 mA cm−2 40 mV Pt/Li-GR, almost negligible change observed tests. addition, Pd/Li-GR catalyst. More impressively, latter displays higher HER when compared other reported Pd-based catalysts comparable performance with commercial Pt/C
