Degradation of Dyes Using High Temperature Stable Anatase Nanosphere TiO2 Photocatalyst
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 6
Abstract
High temperature stable anatase phase TiO2 was prepared by using titanium(III) chloride precursor. The prepared TiO2 powder was characterized using XRD, UV, SEM and TEM for their structural, optical and morphological studies. As prepared amorphous nanospheres become crystalline and shows increase in crystallite size with increase in annealing temperature. The lattice (a/b/c) parameters are calculated from XRD diffraction patterns at different annealing temperatures and reported. Obtained anatase nanospheres was used for the photocatalytic degradation of Crystal violet, Methyl red, Thymol blue and Congo red dyes using UV irradiation. The prepared TiO2 photocatalyst shows good catalytic activity in the order of Methyl red>Thymol blue>Crystal violet>Congo red.
