Abstract
Aluminosilicate sols containing Si–O–Al bonds were obtained by dissolving zeolite LTA crystals in HCl solution. The solutions were used as single-source molecular precursors of silicon and aluminum. Highly ordered cage-like mesoporous aluminosilicates with Si/Al ratios ranging from 13 to 35 were synthesized using PEO106PPO70PEO106 triblock copolymer aqueous solution and LTA dissolved in HCl solution under mild acidic conditions.
