Assembly of nanosized mesostructured aluminosilicates by in situ hydrolysis of inorganic precursors

This work emphasizes the influence of the addition of inorganic aluminum salt on the macroscopic properties of mesoporous aluminosilicates. It was found that upon the addition of an optimal amount of aluminum salt followed by a basic catalyst into the system, mesoporous aluminosilicate nanoparticles could be obtained, an observation that had barely been mentioned before. The assembly of nanosized mesostructures was explained by the separate control of silica hydrolysis and condensation in the system, each of which can be effectively manipulated by the aluminum salt and basic catalyst, respectively.
