Vanadium doped few-layer ultrathin MoS₂ nanosheets on reduced graphene oxide for high-performance hydrogen evolution reaction.

ABSTRACT: In this paper, we demonstrate a facile solvothermal synthesis of a vanadium(v) doped MoS₂-rGO nanocomposites for highly efficient electrochemical hydrogen evolution reaction (HER) at room temperature. The surface morphology, crystallinity and elemental composition of the as-synthesized material have been thoroughly analyzed. Its fascinating morphology propelled us to investigate the electrochemical performance towards the HER. The results show that it exhibits excellent catalytic activity with a low onset potential of 153 mV versus reversible hydrogen electrode (RHE), a small Tafel slope of 71 mV dec^-1, and good stability over 1000 cycles under acidic conditions. The polarization curve after the 1000^th cycle suggests there has been a decrement of les
