title: ZnO nanocrystals anchored graphene: in situ solvothermal synthesis and enhanced photocatalytic performance.
abstract: ZnO nanocrystals anchored graphene composite (ZnO/G) was synthesized by a facile in situ solvothermal route. The nanocomposite was characterized by X-ray diffraction (XRD), scanning electron spectroscopy (SEM), transmission electron microscopy (TEM) and Raman spectra (RS). The results indicated that the ZnO particles with an average diameter of ca. 12.6 nm were well-dispersed on the surface of the graphene nanosheets. The optical properties were investigated by fluorescence (PL) and UV diffuse reflectance (UV-VIS). It showed that the nanocomposite displayed a fluorescence quenching property. Furthermore, the nanocomposite showed a remarkably enhanced photocatalytic activity to degrade organic pollutants (MB, MO, Rh-B) under visible light irradiation, with a percentage degradation of MB reaching as high as 99.8% in 60 min.
