Abstract

The metastable phase of TiO₂ (B), one of the polymorphs of titanium dioxide (TiO₂), was prepared by a hydrothermal treatment of a titanium glycolate complex ([Ti₄ (C₂H₂O ₃)₄(C₂H₃O₃) ₂(O₂)₄O₂]^6-) at 473 K for 1-72 h in the presence of H₂SO₄. Characterization by X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed that the obtained samples were composed of single phase TiO₂(B) and the particles had plate-like morphology. After post-synthetic hydrothermal crystal growth (PHCG) applied to the as-prepared sample, thicker plate-like shaped particles were obtained. The photocatalytic activities of the samples obtained by the hydrothermal treatment and after the subsequent PHCG were evaluated in terms of methanol decomposition.
