%X Ordered mesoporous aluminosilicate materials with atomic St/Al ratios of 16-64 weresynthesized at a very low molar ratio of surfactant/silica (0.12) by using aluminium chloride hexahydrate and TEOS as the sources of aluminium and silicon. The resulting materials were characterized by XRD, TEM, FTIR and nitrogen sorption. As the NaOH/Si molar ratio increases from0.2 to 0.6, the products obtained change from hexagonal MCM-41 to cubic MCM-48. The qualityof the product rapidly deteriorates as the aluminium content of the solid increases beyond a certainlimit. XRD shows that the substitution of the silicon by the large aluminium atoms leads to theexpansion of the unit cell.
