In situ growth of MoSe2 nanosheets array on Mo foil: An efficient and durable hydrogen evolution electrocatalyst

Abstract In this letter, we present a facile solvothermal approach for the synthesis of MoSe2 nanosheets array on Mo foil (MoSe2@Mo). Mo foil served both as a Mo precursor and a substrate, on which uniformly distributed MoSe2 nanosheets array was directly grown in situ. The as-prepared MoSe2@Mo catalyst exhibited great hydrogen evolution reaction (HER) electrocatalytic activity and stability in both acidic and alkaline media.
