Three dimensional (3D) hierarchical architectures based onmolybdenum disulfide (MoS2) an d reduced graphene oxide (rGO) are synthesized through a mixed solvothermal method.By simply increasing the amount of graphene oxide (GO) during the synthesis, the 3D assembly of MoS2 can be tunedfrom nanoflowers to cross-linked nanosheets firmly attached torGO. The structural and compositional analysis show that MoS2 nanostructures in the hybrids are constituted by ultrathinnanosheets with single or a few layers, and the GO precursor isreduced as rGO simultaneously. Due to the synergetic effects of rGO nanosheets and controllable assembly in MoS2 ultrathinnanostructures, the resulting nanohybrids show optimizedelectrocatalytic hydrogen evolution properties in 0.5 M H2SO4 solution. This work provides a facile method to increase theefficiency of hydrogen production for MoS2 based materialsand their analogues via a tunable bottom-up assemblystrategy.
