Few-layered ReS2 two-dimensional (2D) semi-conductor nanosheets directly nucleated and grown on reduced graphene oxide (RGO) were synthesized through a facile hydrothermal method.Compared with bare ReS2,the ReS2/RGO hybrid delivers much better electrocatalytic activity for hydrogen evolution reaction (HER) in acidic media.It exhibits a lower Tafel slope of 107.4 mV.dec-1 and a larger current density of-5.2 mA.cm-2 at-250 mV (vs.RHE),compared with ReS2 (152.7mV.dec-t,-3.1 mA.cm-2).The ReS2/RGO hybrid has a unique architecture constructed by highly conductive and porous RGO intetworks,which guarantees easy electrolyte infiltration and efficient charge transfer and provides suffi-cient active edge sites,resulting in enhanced HER perfor-mance.The present synthesis approach can be extended to synthesize other 2D-semiconductor-based composites for energy storage and catalytic devices.
