20. 3 (3.55 g) was resolved into 3.8 mL of aqueous NaOH solution (ca. pH 11.5). Then, this solution was added slowly into the 41 mL of prepared silica-sol at room temperature. Very soon, a white precipitate appeared, and the resulting heterogeneous solution was evaporated at 80°C with stirring to obtain dry powder. Obtained dry powder (5.25 g) was transferred into a Teflon autoclave and added distilled water (1.0 mL). After standing at 140°C for 24 h, an autoclave was cooled down to room temperature, then the white solid was washed with distilled water. Obtained white solid was dried at 90°C for overnight to give the K-LDS.
