Paper Title:
Preparation of High Surface Area Anatase TiO2 by a Low Temperature Hydrothermal Process
  Abstract

Pure anatase TiO2 spheres with mesoporous structure were prepared by a simple urea assisted hydrothermal process at low temperature. The characterization of TiO2 was examined by X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), N2 adsorption-desorption and ultraviolet visible spectrophotometer (UV-VIS). The TEM and N2 adsorption-desorption results confirmed that TiO2 spheres has a mesoporous structure. The surface area of TiO2 annealed at 400 °C is up to 302.3 m2/g with average pore diameter about 4.1 nm. While after annealed at 500 °C, the average pore diameter of TiO2 is about 6.8 nm, but the surface area reduces to 142.6 m2/g
