Abstract
The nanosized η-TiO2 polymorph was prepared by the hydrolysis of titanyl sulfate (TiO)SO4 · xH2SO4 · yH2O. η-TiO2 was studied by X-ray diffraction, X-ray photoelectron spectroscopy, IR spectroscopy, and Raman spectroscopy. Characteristic X-ray data and distinguishing Raman spectrum features were found for η-TiO2,. The surface of η-TiO2 samples contained adsorbed OH− particles and water molecules or water molecules of crystal hydrates. The free specific surface area of samples with crystallite sizes of L = 50 (4) and 60 (5) Å was S = 10.17 (9) and 15.6 (1) m2/g. The characteristics of samples with η-TiO2 were favorable for their use as photocatalysts and adsorbents.
