The present study deals with the synthesis of visible light active CdSrGO
hybrid composite by UV assisted photoreduction of Graphene Oxide (GO)
and its application for the photocatalytic decolorization of dye. The synthesized
samples of CdS and CdS-rGO composites were characterized by the scanning
electron microscopy (SEM) and X-ray diffraction (XRD) to study the morphology
and phase characterization of the samples. The developed hybrid composite of
CdS-rGO was studied for both its photocatalytic activity as well as for adsorption
behavior using methylene blue (MB) dye as a model pollutant. The photocatalytic
response of the composite was also compared with commercial TiO2 (PC500 and
TTP) powders and was found to be higher than these photocatalysts. The effect of
rGO concentration on adsorption capacity and photocatalytic response of CdS-rGO composite revealed
that rGO plays an important role in the enhancement of photocatalytic performance of CdSrGO
composite for the photocatalytic decolorization of MB under visible light irradiation.
