Abstract
TiO2 nanoparticles attracted much attention due to photocatalytic activity and solar energy applications. The present work demonstrates the preparation of undoped and Fe doped nanoparticles of TiO2 by co-precipitation procedure at 450 °C. From XRD measurement the mean size of crystallite was estimated by Debye Scherer and W-H plot technique. The morphological study of spherical sized nanoparticles was carried out by Scanning electron microscopy. EDS results show signs of no impurity. The optical band gap values of undoped and doped samples were determined to be 3.35 and 3.25 eV for direct bandgap correspondingly.SEM and EDS are in good agreement with XRD results.
