以聚合羟基金属离子为客体物质，在蒙脱土的层间进行插层柱撑，制备出具有层柱结构的柱撑粘土TiPILCs、Al-PILCs、Zr-PILCs，用比表面和孔径分布、吸附脱附等温线、XRD对柱撑粘土的孔结构进行了研究．聚合羟基金属离子可进入钠基土层间进行有效的柱撑，形成的柱撑粘土其比表面和孔径大幅增加．聚合羟基钛离子的插层柱撑过程导致粘土c-轴向层结构改变，引起径向孔径的增加，形成了新的层柱状中孔结构．XRD显示Ti—PILC上的TiO2以锐钛矿柱子的形式存在于层间．

Pillared clays Ti-PILCs, Al-PILCs and Zr-PILCs were synthesized from Na-Mt. The BET surface area, N2 adsorption/desorption isotherms, pore size distribution and XRD of pillared clays were studied. The BET surface area and pore size of clays were largely increased and new pillared layered mesoporous stucture are formed after the pillaring course. XRD showed that the TiO2 pillars existing in the layer of clays were anatase.
