摘要：

Among many transition-metal chalcogenides, metal selenide NiSe2 owns inherently high conductivity and exhibits stability in both acidic and alkaline electrolytes, in recent years, NiSe2 based materials have been attracted special attention in energy storage and conversion field. Herein, the NiSe2 and Co or Fe ions doped NiSe2 microparticles were synthesized via one-step solvothermal method. It is worth noting that the as-prepared metal selenide catalysts, especially Co, Fe-doped NiSe2 (Fe0.08Co0.09Ni0.83Se2) catalyst exhibits an excellent oxygen evolution reaction activity in alkaline electrolyte with a very low overpotential of 268 mV at a current density of 10 mA cm(2) and a long-term robust durability.
