Kurzfassung:
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by
electrochemical oxidation of titanium foil in an acid electrolyte. In order
to alter the crystallinity and the morphology of films the as-anodized
amorphous TiO2 nanotube films were sintered at elevated temperatures. The
evolution of the morphology was visualized via scanning electron microscopy
(SEM), while the crystalline structure was investigated by X-ray diffraction
(XRD) and Raman spectroscopy. The chemical composition was studied by X-ray
photoelectron spectroscopy (XPS). The effects of crystallinity and
morphology of TiO2 nanotube (NTs) films on photocatalytic degradation of
methyl orange (MO) in an aqueous solution under UV light irradiation were
also investigated. The TiO2 nanotubes sintered at 650?C for 30 min had the
highest degree of crystallinity and exhibited the best photocatalytic
activity among the studied TiO2 nanotube films.
