Abstract
The synthesis of Fe3+-TiO2 nanoparticles (NPs) derived from peroxytitanium complex carried out using hydrothermal method. Pure TiO2 and Fe3+ doped TiO2 powders were characterized to study their structural, compositional, morphological and optical properties. The X-ray diffraction patterns shows crystalline pure anatase TiO2 and crystallite size decreases from 10.17 to 8.25 nm with addition of Fe3+ ion. FE-SEM micrographs reveal well diffused aggregates with nanograin morphology. The efficiency of antibacterial activity against E. coli was studied under different physicochemical parameters. The antibacterial activity varies with concentration of Fe3+ in TiO2 matrix against E. coli bacteria. The antibacterial activity was increased with increasing Fe3+ content in TiO2 NPs and the highest antibacterial activity was observed for 2.15 wt.% Fe3+-TiO2.
