synthesized by the method of direct hydrothermal synthesis. Their properties have been
investigated using X-ray phase analysis and X-ray fluorescent analysis, high-resolution
transmission electron microscopy, luminescent spectroscopy and Raman scattering. It has
been ascertained that the Fe/TiO 2 , Mn/TiO 2 , Zn/TiO 2 , TiO 2 titania nanotubes possess the
structure of Na 2 Ti 2 O 4 (OH) 2 . The structure of Cd/TiO 2 titania, probably, is mixture of
anatase and rutile phases. We have found that Fe, Mn, Zn, Cd, Ni does not form solid
solution with TiO 2 , and these metals are located in interlayer space. The mechanism of
nanotube formation has been briefly discussed.
Keywords: titania, direct hydrothermal synthesis, nanotube.
