For more energy-efficient and economical hydrogen production, highly active noble metal-free hydrogen evolution catalysts are a priority for all. Herein, we report a facile one-pot hydrothermal synthesis of CoSe2 nanoparticles with their electrocatalytic performance for hydrogen evolution reaction. The synthesized CoSe2 nanoparticles have an average diameter of 50-70 nm with a uniform distribution. They also exhibited good electrocatalytic performance for hydrogen evolution reaction with the onset overpotential and Tafel slope of 140 mV and 95 mV/dec, respectively. The results provide a facile and effective way for the exploration of efficient Co-based HER catalysts.
