Se-NiSe2 hybrid nanosheet arrays with self-regulated elemental Se for efficient alkaline water splitting

Xiang Peng et al.

Summary: Hybrid nanosheets of Se-NiSe 2 exhibit excellent electrocatalytic activity for water splitting, and a high-efficiency bifunctional electrocatalyst is achieved by controlling the ratio of ionic selenium to elemental selenium on carbon cloth. The optimized electrocatalyst shows low overpotentials and high current densities for hydrogen and oxygen generation in 1.0 mol L -1 KOH. Density functional theory calculations reveal that surface-adsorbed elemental selenium optimizes the electron environment and the adsorption/desorption free energy of hydrogen/water. The appropriate ratio of ionic selenium to elemental selenium improves the catalytic activity and kinetics, and the optimized adsorption amount of elemental selenium balances the interactions between them.
