Abstract: |
A series of Fe3+-doped TiO2 nanoparticles (Fe2O3/TiO2) were successfully prepared via hydrothermal treatment. Scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), and UV-visible spectroscopy (UV-Vis) were employed to characterize the morphology, crystal structure, surface structure, and optical absorption properties of the samples. Results showed that a large number of feather-like nanoparticles existed, indicating that these materials had a large specific surface area. Fe3+ ions were possibly well distributed in the lattice structure of TiO2 and partially replaced Ti4+ which caused a broadening of the spectral response of TiO2 and also caused defects in the crystal structure.
