Title: Effects of hydrothermal post-treatment on microstructures and morphology of titanate nanoribbons

Abstract

Titanate nanoribbons were prepared via a hydrothermal treatment of rutile-type TiO{sub 2} powders in a 10 M NaOH solution at 200 deg. C for 48 h. The as-prepared titanate nanoribbons were then hydrothermally post-treated at 150 deg. C for 12-36 h. The titanate nanoribbons before and after hydrothermal post-treatment were characterized with FESEM, XRD, TEM, UV-VIS and nitrogen adsorption-desorption isotherms. The results showed that the hydrothermal post-treatment not only promoted the phase transformation from titanate to anatase TiO{sub 2}, but also was beneficial to the removal of Na{sup +} ions remained in the titanate nanoribbons. After hydrothermal post-treatment, the TiO{sub 2} samples retained the one-dimensional structure feature of the titanate nanoribbons and showed an obvious increase in the specific surface area and the pore volume.
