Microstructural control of mesoporous bulk composed of TiO(2)-derived titanate nanotubes.
The mesoporous bulks composed of TiO(2)-derived titanate nanotubes fabricated from a hydrothermal treatment of commercial TiO(2) particles in a concentrated NaOH aqueous solution were obtained by a hydrothermal hot-pressing (HHP) method and subsequent steam-curing process with HCl solutions. The mesopore size and sodium concentration for the bulky TiO(2)-derived titanate nanotubes were dependent on the treatment conditions on the steam curing process with HCl solutions. The effect of the sodium concentration (Na/Ti) on microstructures were examined on the steam curing process for the application of the bulky TiO(2)-derived titanate nanotubes to several new fields.
