The present work reports the hybridization of ZnO nanostructures on reduced graphene oxide (rGO) surfaces and the evaluation of emission and photocatalytic properties. The reduced rGO, ZnO and rGO:ZnO hybrid nanostructures were prepared by the modified Hummer’s and solvothermal methods, respectively. The number of layers and hybridization of ZnO nanostructures on rGO surface were confirmed through high resolution transmission electron microscopy and transmission electron microscopy analyses. Raman and Fourier transform infrared spectra confirmed the hybridization of graphene and ZnO nanostructures. The photoluminescence measurement was done at 325 nm excitation and the emission properties were considerably altered through the hybridization process. The photocatalytic properties were evaluated against Acid Blue 113 (AB 113) dye and the prepared materials exhibited excellent photocatalytic properties. The degradation efficiency was significantly improved for the rGO:ZnO hybrid nanostructures.
