In this paper, mixed aluminum and copper pillared clays (Al,Cu-PILCs) with different percentage of Cu and copper impregnated aluminum pillared clay (Cu@Al-PILC) were prepared using a bentonite sample. The samples were characterized by X-ray diffraction, N2 adsorption-desorption and Fourier transformed infrared spectroscopy. The results showed bentonite had a main reflection of montmorillonite that characterized by basal spacing, increased by pillaring. The specific BET surface area, total surface area and micropore volume of Al-PILC decreased in Cu@Al-PILC but increased in the case of mixed metal pillars and the maximum of these parameters related to Al,Cu15-PILC. Maximum weight percentage of copper was in Cu@Al-PILC therefore it contained higher percent of copper and its catalytic properties increased. FTIR result of samples confirmed the successful intercalation of Cu.
