Alkali metal (Li+, Na+, K+) intercalated titanate nanotubes have been
studied by vibrational spectroscopy (Raman and FT-infrared), X-ray
diffraction, and electron microscopy. The vibrational spectroscopic data
shown that the most affected vibrational mode is that related to Ti-O
bond whose oxygen is not shared among the TiO6 units of the framework
structure. A correlation between vibrational frequency shifts and
intercalated metal was found, thus showing that vibrational spectroscopy
is very useful for probing metal intercalated titanate nanotubes. Our
results provide good evidences that the structure of titanate layers in
titanate nanotube, a subject of long debate in the literature, is
similar to trititanates (like Na2Ti3O7). (C) 2010 Elsevier B.V. All
