Abstract
The present work focus on the development of an effective process for the production of undoped and Cr doped TiO2 nano powders by microwave technique. The influence of Cr doping on the structure, phase, vibrational bands and optical properties of TiO2 were discussed. The X-ray diffraction patterns of the nanoparticles revealed preferentially oriented (101) anatase phase for TiO2. Fourier transform infrared spectral analysis confirmed the presence of anatase phase for both pure and Cr Doped TiO2. The UV–Visible spectra revealed the increase in absorption band with Cr doping when compared with undoped TiO2 nano particles, and optical band gap decreased slightly with Cr doping. SEM micrographs show spherical shaped grains of TiO2 with high homogeneity, with a subsequent reduction in agglomeration of particles with Cr doping suggesting its potential application for better photo catalytic activity.
