Herein, we demonstrated the highly active and stable composites of molybdenum diselenide/carbon cloth (MoSe2/CC), molybdenum diselenide/nickel foam (MoSe2 /NF), molybdenum diselenide (MoSe2/graphene/NF) electrocatalysts. The electrochemical hydrogen evolution reaction (HER) performance revealed that MoSe2/graphene/NF electrocatlyst have a platinum-like activity with overpotential 92 mV at 10 mAcm(-2) and a small Tafel slope of 42 mV dec(-1) in an acidic medium, which is the best among the non-noble metal hydrogen evolution catalysts. Our experimental findings validated by first-principle calculations using density of states near the Fermi level which increased the carrier concentration of electron and mobility for superior HER performance.
