Preparation of Al-MCM-48 and Ti-MCM-48

Abstract:

In system of cetyltrimethylammonium bromide (CTAB), tetraethyl orthosilicate (TEOS) and sodium hydroxide, the mesoporous sieves MCM-48 with hetero atom could be synthesized by adding different aluminum and titanium sources. The results showed that M41S family of hexagonal (MCM-41), cubic (MCM-48) and lamellar phase (MCM-50) could be synthesized respectively through hydrothermal method by adjusting the alkalinity in synthesis gel exactly.
