Abstract
MoSx nanoparticles–graphene hybrid film was deposited onto a glassy carbon electrode by a facile one-step electrodeposition approach using MoS42− and graphene oxide as precursors. As a novel hydrogen evolution reaction (HER) electrocatalyst, this hybrid film exhibits highly catalytic activity and good stability.
•We demonstrate the first one-step fabrication of graphene film-confined MoSx nanoparticles.•Such hybrid film is used as a novel HER electrocatalyst in acidic solution.•Such hybrid film shows high HER activity and good stability.
