a: Average crystalline size of TiO2 was determined on the basis of the broadening of the anatase diffraction peak using the Scherrer equation.
b: The BET surface area was determined by multipoint BET method using the adsorption data in the relative pressure ( ) range of 0.05–0.2.
c: Pore volume, porosity, and average pore size were determined by nitrogen adsorption volume at the relative pressure of 0.994.
