Mesoporous aluminosilicate Al-MCM-41 with Si/Al=33, 52, 75, and 114 were synthesized using cetyltrimethylammonium bromide (CTAB) as the structuring agent. The materials were characterized using several techniques. The mesoporous structure was confirmed by X-ray diffraction (XRD) technique. The surface area, pore size and pore volume were given by BET equation and BJH method using nitrogen sorption...
