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