1TiO2 by sol-gel method.
2From XRD analysis.
3From the equation SSA = 6000 * ( )−1, where SSA is the calculated specific surface area, is crystallites size (nm) and is TiO2 density (g/cm3), based on the assumption of spherical and nonporous particles [48].
4From DLS instrument.
5From UV-Vis spectra.
