Nanotechnology is one of the new methods technologies, which can use bottom- up approach with low temperature chemical growth to synthesize nanomaterial particle. There are diverse aspects of the preparation and characterization of nanoscopic ZnO, and composite ZnO/TiO2 materials. In this study, ZnO NPs were prepared by hydrothermal method, using 1: 1.5 ratio of Zinc acetate diyhdrate to Sodium hydroxide. Then prepared ZnO NPs were used with commercial rutile TiO2 NPs a mean diameter about 40 nm, to prepare composite ZnO/TiO2 NPs with ratio 1: 3, which were successfully synthesized by modified hydrothermal method. Different techniques used to investigate the crystal structure, morphology, the chemical composition, UV-visible, and energy band gap of NPs. The XRD confirms that the formation of rutile TiO2 and zincite ZnO NPs phases in the composite structure; the observation shows according to SEM images, ZnO NPs have hexagonal shapes; TiO2 NPs have a tetragonal shape, and ZnO/TiO2 composite present as cubic NPs shape. Also the (EDS) observation shows availability of ZnO, TiO2 and composite ZnO/TiO2 NPs in the sample; and UV-visible light confirms the wavelength range and band gap energy of ZnO, TiO2 and composite ZnO/TiO2 NPs.
