Abstract

The development of high-kinetic catalysts for the hydrogen evolution reaction (HER) in a neutral electrolyte is of great importance but unfortunately remains a challenge so far. Herein, we report hybrids with abundant Ru–S–Sb bonds and engineered ultrathin antimonene (Ru–S–Sb/antimonene) as highly kinetic, active, stable electrocatalysts for the HER in an aqueous neutral electrolyte. Experiments and density functional theory (DFT) calculations reveal that Ru–S–Sb bonds coupling with antimonene synergistically work to promote HER activity. The present study brings us one step closer to understand the structure–composition–property relationships and practical electrolytic H₂ production.
