The present work emphasizes the structural, optical and thermal properties of pure TiO2 and TiO2/ZnO nanocomposite. The samples were synthesized by sol-gel method and characterized by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), Ultraviolet-visible spectroscopy and Thermal gravimetric analysis (TGA). The XRD analysis shows that synthesized TiO2 nanoparticles consisted of only anatase phase and also it revealed the presence of both, TiO2 and ZnO phases in TiO2/ZnO nanocomposites. TEM analysis confirmed that the shapes of TiO2/ZnO nanocomposite are spherical (due to TiO2) and nanorods (due to ZnO) and EDS analysis confirmed that synthesized material has no impurity. Thermal gravimetric analysis (TGA) shows the weight loss of the nanoparticles which is found to take place up to 800°C, beyond this temperature no significant weight loss was observed. The band gap of pure TiO2 and TiO2/ZnO nanocomposite have been estimated from absorption peak and found to be 3.14 eV and 2.82 eV respectively.
