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-TP...
