• 論文の詳細を見る

• The metastable phase of TiO_2(B), one of the polymorphs of titanium dioxide (TiO_2), was prepared by a hydrothermal treatment of a titanium glycolate complex ([Ti_4(C_2H_2O_3)_4(C_2H_3O_3)_2(O_2)_4O_2]^<6->) at 473K for 1-72h in the presence of H_2SO_4. Characterization by X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed that the obtained samples were composed of single phase TiO_2(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.
