|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.
