Preparation of Titanate Nanotubes by Hydrothermal Method
Titanate nanotubes have been directly prepared by hydrothermally treating P25 powders in NaOH aqueous solution. Effect of calcination temperature on crystal phase, morphologies and specific surface area of the as-synthesized nanotubes has been investigated in detail. The Na2Ti3O7 tubular structure could be kept well even after calcination at 600 ℃ and began to transform to Na2Ti6O13 nanorods at around 645 ℃. The specific surface area of the as-synthesized nanotubes was 200.6 m2/g and reached to the maximum of 347.9 m:/g after calcination at 300℃ and then decreased sharply with the further increase of the calcination temperature.
