TiO(2)/ZnS/CdS Nanocomposite for Hydrogen Evolution and Orange II Dye Degradation
Original language description
TiO(2)/ZnS/CdS composites for photocatalytic hydrogen production from water were prepared by homogeneous hydrolysis of aqueous solutions mixture of TiOSO(4), ZnSO(4), and CdSO(4) with thioacetamide. Hydrogen evolution was observed in the presence of palladium and platinum nanoparticles deposited on TiO(2)/ZnS/CdS composites. The morphology was obtained by scanning electron microscopy, the nitrogen adsorption-desorption was used for determination of surface area ( BET) and porosity. The method of UV-VISdiffuse reflectance spectroscopy was employed to estimate band-gap energies of prepared TiO(2)/ZnS/CdS nanocomposites. The photocatalytic activity of the prepared samples were assessed by photocatalytic decomposition of Orange II dye in an aqueous slurryunder UV irradiation at 365nm wavelength and visible light up to 400nm wavelength. Doped titanium dioxide by the CdS increased band-gap energy and doping with ZnS increased photocatalytic activity. The best photocatalytic activity for H(
