| 摘 要： | 用水热离子交换法将过渡金属Ｃｏ＾２＋取代的Ｋｅｇｇｉｎ结构杂多阴离子ＳｉＷｑＯ３７Ｃｏ３（Ｈ２Ｏ）３＾１０－（简记为ＳｉＷｑＣｏ３）嵌入Ｚｎ－Ａｌ型阴离子层状结构粘土层间。通过元素分析，ＸＲＤ和ＩＲ，对产物的组成和结构进行了表征。结果表明，杂多阴离子被嵌入粘土层间后，仍保持原有的Ｋｅｇｇｉｎ结构，并使粘土的层间距从０．８９ｎｍ增加到１．４７ｎｍ，从而得到大层间距的新型层柱微孔材料，值化实验结果表明

| Abstract: | The trisubstituted tungstosilicate heteropolyanion, SiWqO37Co3 (H2O)3(10-) hav-ing Keggin Structure, was intercatated into the interlayer speae of Zn - Al type layered double hydroxide Via both bydrothermal and ion exchange reaction, The pillared product was Charac-teriZed by elemental analysis, XRD and IR, which showsthat the heteropolyanion still remained former Keggin structure and the layered microporous material with large basal spacing of 1 .47nm has been Obtained. Catalytical tests show that the pillered compound has higher catalytic activity for the formation reaction of DOP |
