Abstract:
In this paper, titanium dioxide/tungsten trioxide nanoparticles were synthesized by sol–gel method. Obtained nanoparticles at different calcination temperatures were analyzed and characterized by X-ray Diffraction (XRD), scanning electron microscope (SEM) and Ultraviolet–visible spectroscopy (UV-vis) techniques. The effect of the calcination temperature and mole percent of TiO2 on the Absorption spectra of nanoparticles have been studied.
It has been shown that with increasing calcined temperature and molar percentage of TiO2, the absorption rate of TiO2 / WO3 nanoparticles increased. This process produces more OH radicals and increases the degradation of organic compounds and ultimately improves the photocatalytic properties.
