Abstract: In this letter, the changes of aluminum content, acid amount and catalytic properties of AlMCM-41 after treatment by NaAlO₂ in the presence/absence of cetyltrimethylammonium bromide (CTAB) were studied. The samples were characterized by XRD, N₂ adsorption-desorption isotherm, ²⁷Al MAS NMR and NH₃-TPD. Characterization results revealed that the introduction of CTAB during the modification process played a crucial role in the adjustment of surface properties of AlMCM-41 including distribution of aluminum atoms and acid site numbers, otherwise the original ordered AlMCM-41 would be completely destroyed.
