中文摘要：

以天然杭锦2#土为原料,进行酸化活化,得到酸化杭锦2#土,并进一步以十六烷基三甲基溴化铵作为有机插层剂制备了有机改性杭锦2#土。其FTIR谱图中出现—CH的振动峰,说明插层剂已进入到杭锦2#土层间。再经高温焙烧有机改性杭锦2#土制得介孔杭锦2#土,并应用X射线衍射和扫描电子显微镜对样品进行了晶相和形貌分析,用N2吸附脱附测定其比表面积和孔径,通过傅里叶变换红外光谱和紫外-可见漫反射光谱对样品进行了光谱表征。

英文摘要：

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.
