Few MoS2/RGO hybrids with uniform size were successfully synthesized via hydrothermal method. MoS2/RGO hybrids show excellent visible-light photocatalytic properties. Good photocatalytic stability of MoS2/RGO for the second cycle indicates its promising practical applications. Excellent photocatalytic capability of MoS2/RGO hybrids can be attributed to their enhanced adsorptivity and conductivity.
