Abstract

This paper explores strain-tunable sulfur vacancies around single-atom Ru sites on nanoporous MoS<sub>2</sub> to enhance alkaline hydrogen evolution reaction (HER). Altering the strain amplifies the synergistic effect between sulfur vacancies and Ru sites, increasing reactant density and accelerating HER. The resulting catalyst shows an overpotential of 30 mV at 10 mA cm⁻², a Tafel slope of 31 mV dec⁻¹, and long-term stability.
