Abstract

A mechanism for the formation of trititanate nanotubes in the reaction of TiO₂ and NaOH was studied. The transmission electron microscopy was used to study the composition and structure of the specimens. The surface tension due to an asymmetry related to hydrogen deficiency in the surface layers of the plates was found to be the principal driving force of the cleavage of the trititanate single sheets. It was found that the surface tension together with interlayer coupling energy and Coulomb force, controlled the dimension of the nanotubes.
