摘要

TiO2 and iron-doped TiO2 were synthesized by sol-gel method. TiO(2 )and 0.5 %mol Fe:TiO2 were calcined at 500 and 800 degrees C for 3 h. The synthesized particles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV-VIS diffuse reflectance spectrophotometry (UV/DRS), scanning electron microscopy (SEM) and scanning electron microscope-energy dispersive X-Ray analysis (SEM-EDX). The XRD patterns of all samples that were calcined at 500 degrees C showed only anatase phase. On increasing temperature from 500 to 800 degrees C, the anatase phase transformed to rutile phase. For 0.5 %mol Fe:TiO2, pseudobrookite (Fe2TiO5) phase was observed at 800 degrees C. The particles that contained rutile showed higher antibacterial activities against E. coli, B. subtilis, and S. aureus than anatase phase, under fluorescent irradiation.
