Study of Photocatalytic activity and properties of Transition metal ions doped Nanocrystalline TiO2 prepared by Sol-Gel Method.

摘要

We report the growth of [Fe, Co]_xTiO2 (x=0.01,0.02 &0.04) nanocrystals prepared by Sol-Gel techniqu, followed by freeze-drying treatment at -30°C temperature for 12hrs. The obtained Gel was thermally treated at different temperature like 200,400,600, 800°C. We studied its Structural, Photocatalytic and magnetic properties by using X-ray diffraction, Scanning Electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDAX) and Gouy Balance techniqu. The as-prepared samples are found to be paramagnetic at room temperature. The photoreactivity of transition metal ion-doped TiO2 nanoparticles under UV irradiation were quantified by the degradation of formaldehyde.
