The natural clay named Hangjin2# clay was used as raw materials and cetyltrimethylammonium bromide (CTAB) was used as organo-intercalating reagents to synthesize organic modified clay from acid treated Hangjin2# clay. The results of FTIR show that the modified reagents were intercalated to the layer of Hangjin2# clay. The meso-Hangjin2# clay was prepared with organic modified clay calcinated at 550 ℃ and the crystalline phase and morphology were characterized by X-ray powder diffraction (XRD) and scanning electron microscope (SEM). The surface area and pore volume were analyzed by N2 adsorption desorption, and the characteristics of spectrum were studied via FTIR and UV-Vis(DRS) spectrum.
