The earth-abundant and high-p.r.ormance catalysts are crucial for commercial implementation of hydrogen evolution reaction(HEr).Herein,a multifunctional site strategy to construct excellent HEr catalysts by incorp.r.ting iridium(Ir)ions on the atomic scale into orthorhombic-CoSe2(Ir-CoSe_(2))was *** hydrogen evolution activity in alkaline media such as a low overpotential of 48.7 mV at a current density of 10 mA cm^(-2)and better p.r.ormance than commercial pt/C catalysts at high current densities were found in the Ir-CoSe_(2) *** the exp.r.ments and theoretical calculations,it was revealed that Ir enabled CoSe_(2)to form multifunctional sites to synergistically catalyze alkaline HEr by promoting the adsorption and dissociation of H_(2)O(Ir sites)and optimizing the binding energy for H^(*)on Co *** was noticeable that the electrolytic system comprising the Ir-CoSe_(2)electrode not only produced hydrogen efficiently via HEr,but also degraded organic pollutants(Methylene blue).The cell voltage of the dual-function electrolytic system was 1.58 V at the benchmark current density of 50 mA cm^(-2),which was significantly lower than the conventional water splitting *** was indicated that this method was a novel strategy for designing advanced HEr electrocatalysts by constructing multifunctional catalytic sites for hydrogen production and organic degradation.
