TiO2(B) nanowires and TiO2 anatase nanowires were synthesized by the hydrothermal processing in 10 M NaOH aq. at 150 degrees C followed by the post-heat treatment at 300-800 degrees C. As-synthesized Na-free titanate nanowires (prepared by the hydrothermal treatment and repeated ion exchanging by HCl (aq.) were transformed into TiO2(B) structure with maintaining 1-D morphology at 300-500 degrees C, and further transformed into anatase structure at 600-800 degrees C with keeping 1-D shape. At 900 degrees C, they transformed into rod-shaped rutile grains. Microstructure of these 1-D TiO2 nanomaterials is reported. (c) 2005 Elsevier Inc. All rights reserved.
