abstract The influence of the neutralization process after hydrothermal synthesis on the structure and morphology of titanate nanotubes was investigated by X-ray diffraction, high-resolution transmission electron microscopy and Raman spectroscopy. Well formed nanotubes were obtained during the hydrothermal treatment of anatase in highly alkaline conditions. Synthesis at 150 degrees C led to the formation of layered titanate structure with the general formula Na2-xHxTi2O5 center dot 1.8 H2O, where x depends on pH. The tubular morphology is not dependent on the Na+/H+ ion exchange reaction.
