a
Initial gel: SiO2: 0.025TiO2: xOSDA: yH2O.
b

c
Measured by inductively coupled plasma (ICP).
d
Specific surface area calculated from the nitrogen adsorption isotherm using the BET method. Smicro (micropore area), Sext (external surface area), and Vmicro (micropore volume) calculated using the t-plot method.
e
Total pore volume at P/P0 = 0.995.
f
V meso = Vtotal − Vmicro.
g
FT-IR relative intensity of the bands at 960 and 800 cm−1.
