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⁺.
