In this work, we have successfully synthesized ternary nanohybrid composite, ZnS-Ag 2 S wrapped with reduced graphene oxide (RGO) using hydrothermal method without any surfactant. We have accessed the photocatalytic ability of ZnS-Ag 2 S-RGO nanocomposite using the oxidation of Rhodamine B (RhB) under simulated sunlight irradiation. The superior photocatalytic ability of ZnS-Ag 2 S-RGO compared to bare ZnS, was ascribed to an efficient charge transfer from ZnS to Ag 2 S and graphene sheets. The recyclability results also demonstrated the excellent stability and reliability of the ZnS-Ag 2 S-RGO. In addition to the excellent photocatalytic degradation properties, the synthesized ZnS-Ag 2 S-RGO nanocomposite exhibited near white light emission, which implies that careful design and control of the composition could be lead to find application in near UV-white LEDs. The present work provides new insights into the synthesis and characterizations of ternary ZnS-Ag 2 S-RGO nanocomposites and its wide applications in the environmental protection issues.
