Journal of Physics and Chemistry of Solids, Elsevier, 2009, 69 (7) This is a PDF file of an unedited manuscript that has been accepted for publication.

Abstract: Photocatalytic active TiO 2 /ZnO composite was prepared by homogeneous hydrolysis of mixture of titanium oxo-sulphate and zinc sulphate in aqueous solutions with thioacetamide and subsequent annealing at temperature of 600 °C. The prepared samples were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), High resolution transmission microscopy (HRTEM). The nitrogen adsorption-desorption was used for surface area (BET) and porosity determination. The photoactivity of the prepared TiO 2 /ZnO samples was assessed by the photocatalytic decomposition of Orange II dye in aqueous slurry under irradiation of 254 nm and 365 nm wavelength. Under the same conditions, the photocatalytic activity of a commercially available photocatalyst (Degussa P25), the pure anatase TiO 2 nanoparticles and cubic ZnO were examined.

“…Experiments were also performed to investigate the reusability and stability of the synthesis ZnO. Liao et al 20 produced a novel binary oxide photocatalyst ZnO/TiO 2 prepared by solgel method using citric acid as a complex reagent and its photocatalytic activity was investigated. It was showed that the addition of ZnO could enhance the activity significantly, and sulfating ZnO/TiO 2 with sulfuric acid resulted to dramatic enhancement, the degradation ratio of methyl orange could be up to 71.9% compared with 55% of degradation of ZnO/ TiO 2 catalyst.…”

Photocatalysis has been applied to decompose the waste and toxic materials produced in daily life and in the global environment. Pure TiO 2 (Zn-TiO 2 -0) and Zn-doped TiO 2 (Zn-TiO 2 -x, x = 3-10 mol %) samples were synthesized using a novel sol-gel and ammonia-evaporation method. The Zn-doped TiO 2 samples showed high photocatalytic activity for the degradation of methylene blue (MB). The physicochemical properties of the samples were investigated using XRD, SEM, ICP, DLS and BET methods. In addition, the most important measurement of photocatalytic ability was investigated by a UV-vis spectrophotometer. The effects of the mol % of zinc ion doping in TiO 2 on photocatalytic activity were studied. Among the mol % Zn ions investigated, the Zn-TiO 2 -9 sample showed the highest photoreactivity. This sample removed 91.4% of the MB after 4 h, while the pure TiO 2 only removed 46.4% of the MB.
