“…All calculations were carried out based on Vienna Ab initio Simulation Package (VASP) software. − The generalized gradient approximation (GGA) of Perdew–Burke–Ernzerhof (PBE) exchange correlation functions was used to describe electron exchange and correlation interactions . The cutoff energy was set to be 400 eV and the Brillouin zone was divided by 2 × 2 × 1 sample points for geometric optimization of the catalyst surface.…”

The development of highly efficient nonnoble metals toward hydrogen evolution reaction (HER) electrocatalysts is significant for producing hydrogen via water electrolysis. Selenides are becoming increasingly attractive owing to their excellent HER activity. Herein, CoSe2 nanorods were successfully manufactured on a carbon cloth (CC) and selenium vacancies were obtained using a plasma cleaner (CoSe2-VSe/CC) to enhance their intrinsic catalytic activity. The synthetic catalyst exhibited a lower overpotential of 88 mV at 10 mA cm–2 in 1 M KOH and high durability over 100 h at 100 mA cm–2, which can be ascribed to the increased electrochemical surface area and rapid electron transfer. In addition, density functional theory (DFT) calculations showed that introducing Se vacancies optimized the hydrogen adsorption energy on the Se site and reduced the transition-state energy barrier of water dissociation. This study laid a firm foundation for preparing high-performance and stable electrocatalysts via anion defect engineering.
