Preparation and Photocatalytic Property of Iron-doped TiO2 Nanoparticles
Abstract:
The iron-doped TiO2 nanoparticles in size of 60~70 nm were prepared by a sol-gel method, followed by freeze-drying treatment for 2 h. TG-DTA, XRD, UV-Vis, LDRSA and SEM observation and techniques were used to characterize the ultrafine particles. The presence of iron ion in TiO2 crystalline was found to increase the photocatalytic activity of TiO2 in degradation of phenol. The iron-doped TiO2 with different mass percentage of Fe3+ were compared with pure TiO2 when being used as photocatalyst in degradation of phenol. The best catalytic activity was observed in TiO2 with 0.05% doped Fe3+.
