- 論文の詳細を見る
TiO2 nanofibers were synthesized from natural leucoxene mineral via a hydrothermal process. The shapes, crystalline structure, shape transformation, phase transformation, and specific surface area of the resulting nanostructured materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer--Emmett--Teller (BET) surface area measurements. The size of prepared nanofibers was about 12--58 nm in width and about 3--22 μm in length. The BET surface area of the prepared sample was about 55 m2/g. Obtained nanofibers were preliminarily applied as photocatalysts for hydrogen evolution and electrodes for dye-sensitized solar cells (DSSCs).
