Facile fabrication of hierarchical hollow microspheres assembled by titanate nanotubes.
Hierarchical hollow microspheres assembled by titanate nanotubes were fabricated via a hydrothermal process. During the entire process, the hydrous titanium oxide microspheres served as a template and source of titanate ions and H(2)O(2) was used to facilitate the conversion of titanate sheets into nanotubes in low-concentration NaOH (0.1 M). Furthermore, this synthesis route is more friendly than the previous hydrothermal synthesis of TiO(2)-derived nanotubes in a highly alkaline (10-15 M) medium.
