Abstract. Fe/TiO 2 , Mn/TiO 2 , Zn/TiO 2 , Cd/TiO 2 , Ni/TiO 2 titania nanotubes were 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.
