MoS2/RGO hybrids was successfully synthesized via hydrothermal method. The MoS2 nanoflakes grown on the surface of the graphene were uniform and compact from the TEM images. Through the HRTEM images, we conclude the layer number of MoS2 nanoflakes is in the range of 2-6. Photocatalytic experiments have been performed to verify the excellent photocatic performance of MoS2/RGO hybrids. The methylene blue (MB) was completely decomposition by MoS2/RGO hybrids within 55 and 75 min under the UV and VIS irradiation, respectively. It is much better than the photocatalytic performance of P25 (nano TiO2 powder, the current commercial photocatalyst), especially under the VIS irradiation. Good photocatalytic stability of MoS2/RGO hybrids was proved through the secondary loop test, which further indicates its promising practical applications. We suggest that the excellent photocatalytic capability of MoS2/RGO hybrids can be attributed to their enhanced adsorptivity and conductivity because of the synergistic effect between the few layer MoS2 and the graphene.
