Abstract

RuAgW/C demonstrates an excellent mass specific exchange current density (j_0,m) of 442.9 A g_Ru⁻¹ superior to that of Pt/C (329.7 A g_Pt⁻¹) toward the alkaline hydrogen oxidation reaction (HOR) primarily owing to weakened hydrogen binding energy (HBE) and strengthened hydroxide binding energy (OHBE).
