Solvothermal synthesis of mesoporous TiO2 microspheres with tailored pore size and specific surface area
- 285 Downloads
Mesoporous TiO2 microspheres with high specific surface area were synthesized by a template-free solvothermal method with the aid of urea. The phase structure, morphology, pore and optical properties were characterized by XRD, SEM, N2 adsorption–desorption and UV–Vis diffuse reflectance spectra. By controlling the urea concentration, size, specific surface area, pore size and optical property of the mesoporous TiO2 microspheres can be tuned.
