Abstract

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 55m2/g. Obtained nanofibers were preliminarily applied as photocatalysts for hydrogen evolution and electrodes for dyesensitized solar cells (DSSCs). © 2011 The Japan Society of Applied Physics.
