杂多阴离子柱撑水滑石类层柱材料中层柱相互作用研究

合成了具有不同组成的类水滑石层状化合物和杂多酸，据此制备了一系列杂多阴离子柱撑水滑石，用ＩＲ光谱、ＤＴＡ等方法研究了此类层柱材料中层与柱的相互作用，发现类水滑石层状化合物中的Ｍ＾３＋离子的种类和具有Ｋｅｇｇｉｎ结构的杂多阴离子的组成元素，无论处于四面体中、还是位于八面体中，对层柱的相互作用皆有明显影响，此外，这种相互作用还导致杂多阴离子中四面体和八面体对称性及相关性质的改变。

Studies on the Interaction Between the Layers and Pillars of Hydrotalcite-Like Compounds Pillared with Heteropolyanions

Hydrotalcite-like compounds (HTIs),heteropolyanions with different composetions,and their pillared products were prepared.The interactions between the layers and pillars of the pillared products were investigated by IR spectra and DTA methods. Tge results show that the M3+ ions in the HTIs and the component elements of the heteropolyanions with Keggin structure, which can either exist in the tetrahedral or in the octahedral positions, have significant effects on the interactions between the layers and pillars. In addition,this interaction usually results in changes in the symmetry and relative properties of the heteropolyanions.
