Al-pillared clay (Al-PILC), mixed-Cr/Al PILCs (CrAl033-PILC, CrAl1-PILC) and Cr-pillared clay (Cr-PILC) were synthesized using bentonite clay from the Hancili region in Turkey. Metal yerlestirilmis sutunlu kil orneklerinin sivi azot sicakligindaki N-2 adsorpsiyon/desorpsiyon izotermleri elde edilmis ve izoterm verileri kullanilarak gozenek yapilari ile belirlenmistir. Adsorption and desorption isotherms of N-2 at the temperature of liquid nitrogen of the metal-incorporated PILC samples were obtained and by using isotherm data, pore structures were determined by Density Functional Theory (DFT) and Dubinin-Radushkevich (DR) methods. It was observed that The Density Functional Theory (DFT) model was consistent with the experimental data for metal-incorporated pillared clay samples. The most DFT and DR micropore volume values were obtained for CrAl033-PILC calcined at 573 K as and 0.080 cm(3)g(-1) and 0.138 cm(3)g(-1). It was shown that micropore volume values obtained by DR method are consistent with the ones determined by SF method.
