MoSe2–Pt hybrid nanoflowers were prepared by a one-pot hot-solution colloidal synthetic method, the samples were characterized by various analytical testing techniques, and their electrocatalytic hydrogen evolution reaction performance was studied. Due to the synergistic effect of the MoSe2 substrate and Pt nanoparticles, the MoSe2–Pt hybrid nanoflowers exhibited enhanced hydrogen evolution performance compared with individual MoSe2 nanoflowers. We found that the highly nanostructured MoSe2–Pt catalyst presented excellent durability under strong acidic conditions with an onset overpotential as low as 100 mV and a Tafel slope of ~ 85 mV dec−1. This preparation method can also be extended to obtain other catalysts based on MoSe2 for electrocatalysis.
