Abstract

Hexagonal and lamellar aluminosilicate mesostructures with a Si/Al ratio close to 1 have been obtained by a new two-step synthetic route. The precursor aluminosilicate Al4Si4O12(OH)math image and the surfactants organize into mesophasic precipitates when the corresponding solutions are mixed together. Further condensation and structure ordering of the precipitated phases can then be achieved by vapor-phase treatment or refluxing isopropyl alcohol treatment leading to mesostructural materials.
