title: Structural features of titanate nanotubes/nanobelts revealed by Raman, X-ray absorption fine structure and electron diffraction characterizations.
abstract: High-purity nanotubes and nanobelts could be controllably obtained in hydrothermal treatments of anatase TiO(2) in concentrated NaOH solution depending on treating temperature and duration. Their structural features were studied employing X-ray diffraction, Raman, X-ray absorption fine structure, and electron diffraction characterizations. The results reveal that both the nanotubes and nanobelts might be of layered titanate structure. The similarity and difference among the nanotubes/nanobelts and other bulk titanates represented by trititanate H(2)Ti(3)O(7) and lepidocrocite-type H(0.7)Ti(1.825) square(0.175)O(4.0).H(2)O were also presented.
