Nanotubular metal oxide ceramic materials have attracted a great attention last years due to their unusual physico-chemical properties and potential use in many energy and bio-medical applications. Although the range of materials capable of forming multiwalled nanotubes is constantly growing, a comprehensive mechanism of their formation, which would not only provide an efficient way of controlling nanotube morphology, but would also allow formulation of the synthesis conditions for new nanotubular materials, is still under development. A general overview of hydrothermal routes for synthesis of several metal oxide nanotubes will be discussed. The commonality in the mechanisms of formation of these nanotubes will be identified and analysed. The driving forces for spontaneous folding of nanosheets into nanotubes will be considered.
