Abstract
Nanocrystalline anatase TiO 2 was prepared by a facile sol–gel route at a temperature of 65 °C under mild conditions. Tetrabutyl titanate was used as a titanium precursor, glacial acetic acid was used as an inhibitor, and anhydrous ethanol was used as a solvent. XRD, TEM, FT-IR and XPS spectra were applied to characterize the crystal phase, microstructure, and other physicochemical properties of the nanoanatase TiO 2. The results showed that as prepared ellipse-shaped anatase TiO 2 with an average diameter of 7 nm, which is rich in surface hydroxyl groups, was found to exhibit high dispersibility.
