Abstract

One-dimensional titanate nanotubes and nanowires were synthesized by hydrothermally treating TiO2 nanoparticles (P25) with an aqueous NaOH solution in a revolving autoclave. The effect of the reaction temperature and time on the morphology and crystal structure of titanate nanomaterials was systematically studied. When the hydrothermal treatment was carried out in a revolving autoclave, nanotubes with NaxH1-xTi 2-x/4?x/4O4×H2O crystal structure were obtained and favor to self-assemble in shape of clusters and bundles, and nanotube bundles tended to transform into nanowires with the crystal structure transforming into NaxH2-xTi 3O7 within 48 h at a hydrothermal temperature higher than 130 °C. Based on the experimental results, a possible mechanism for the formation of titanate nanotube by wrapping of nanosheets and nanowires formed via the cooperation of oriented attachment and Ostwald ripening was proposed.
