N2 adsorption/desorption analysis confirmed the above picture (see Supporting information): An increase in H2O/SiO2 ratio with a simultaneous decrease in Si/Al ratio shifted the pore size distribution maximum from the 5–10 nm range for the Zol1–3 samples to 40–50 nm for Zol6–7 and even out of the measurement range (≥300 nm) for the applied analysis method for Zol11–Zol12.
