Tailoring nanoporous aluminosilicates with well-defined Al(OSi)4 sites using dimethylsilanol-modified cage siloxanes and ammonium cations

Abstract

The precise synthesis of nanoporous aluminosilicates with well-defined Al(OSi)4 sites was achieved using rigid cage siloxanes. Organic ammonium cations served not only as counterions for the negatively charged framework but also as modulators of pore characteristics. Treatment with an aqueous NH4Cl solution generated Brønsted acid sites. This work paves the way for designing nanoporous aluminosilicate materials.
