N2  - In this study, CdSnanoparticles were synthesized in different sizes and morphologies using twodifferent methods. First, the synthesis of both cauliflower-type CdS microspheresand CdS nanoflower-type microstructures by hydrothermal synthesis was carriedout in a steel reactors with teflon chamber. While polyethylene glycol andthioacetamide were used in the synthesis of cauliflower-type CdS microspheres,thiourea was used as a sulfur source in the synthesis of nanoflower CdS microstructures.Spherical CdS and Ag/CdS nanoparticles having a diameter of about 200 nm wereprepared by the sol-gel method. In this method, polyethylene glycol is used asa stabilizer by providing the control of the growth of nanocrystals due to itshigh solubility in water and high viscosity. Using both methods, CdS micro- andnanostructures were successfully prepared in different sizes and shapes. Theseparticles were used for photodegradation of methyl orange (MO) dye. The resultsshow that the CdS particles synthesized may have potential uses in waste waterapplications by photodegrading the MO dye. Energy band gaps of CdS structureswere determined by fluorescence spectroscopy measurements. X-ray diffraction(XRD), transmission electron microscopy (TEM) and scanning electron microscopy(SEM) devices have been used to characterize structures. In addition, UV-visspectrophotometer was used for removal of MO dye from waste water and thepercentage of dye degradation and adsorption capacity (qe) of CdS particleswere calculated.
