Nanosized beta-zeolites (BEA) with different SiO2/Al2O3 ration were hydrothermally synthesized by using tetraethylammonium hydroxide (TEAOH) as SDA and a small amount of cationic surfactant containing siloxane moiety: [3-(trimethoxysilyl)-propyl]octadecyldimethylammonium chloride (ODSCI). Among them, BEA100 with SiO2/Al2O3 ration of 100 showed spherical morphology with size of 50-100 nm, and all aluminum species are tetrahedrally incorporated in the framework.
