Synthesis, Characterization and Gas Adsorption of Titania Nanotubes
Titania nanotubes (TNTs) have been successfully synthesized by hydrothermal treatment of anatase TiO2 powder in NaOH solution at 110°C for 90 hours and then annealed at the temperature of 400°C. The morphology and crystalline structure of the nanotubes were characterized by using transmission electron microscopy (TEM) and X-ray diffraction (XRD). The average specific surface area of the particle was probed using gas adsorption-desorption measurements, and average particle size was calculated from the specific surface area. Based on the microscopic observations on the transformation process, it indicated that the formation of nanotubular products remained in their shape after the annealing process. While XRD results confirmed the nanotubes were composed of pure anatase TiO2 nanoparticles.
