Nanostructured ZnO/CdS composites were synthesized using hydrothermal method by varying the sulphur source; thiourea (TU) and thioglycolic acid (TGA). Pure ZnO and two samples of CdS were prepared by varying the sulphur source in order to compare the results of the nanocomposite with the pure nanomaterials. X-ray diffraction analysis shows the average particle size of the ZnO/CdS (TU) and ZnO/CdS (TGA) nanocomposite to be 12.81 nm and 25 nm, respectively. High resolution TEM analysis shows the particle size of ZnO/CdS (TU) and ZnO/CdS (TGA) to be 12 and 17 nm respectively. UV- visible- reflectance spectra were recorded and the band gaps were estimated to be 2.4 eV and 2.84 eV for ZnO/CdS (TU) and ZnO IR/CdS (TGA). The porosity of ZnO/CdS (TU) was 14 nm and ZnO/CdS (TGA) was 2.5 nm. The photocatalytic activity for the degradation of Mordant black 11 dye under sunlight was studied.
