| 摘 要： | 通过离子交换法, 将含钛过渡金属离子一、三取代钨硅、钨磷过氧杂多配合物嵌入Zn2Al类水滑石中, 获得了柱撑化合物, 并用XRD, IR, XPS, 元素分析等手段对产物的结构和组成进行了表征。结果表明, 过氧杂多阴离子进入水滑石层间后, 水滑石的层间距从0.92nm增大到1.47nm, 且O2^2^-链没有被破坏。柱撑产物在环己烯氧化反应中显示优良的催化性能。

| Abstract: | The Keggin-ion [SiW11(TiO2)O39]^6^-, [SiW9(TiO2)3O37]^-^1^0, [PW11(TiO2)-O39]^5^-, [PW9(TiO2)3O37]^9^- intercalated Zn2Al hydrotalcite-like compounds were prepared by means of direct ion-exchange reaction in aqueous solution, and were characterized by elemental analysis, XRD, IR and XPS spectra. The interlayer space of the pillared products increased from 0.92nm to 1.47nm with the peroxoheteropolyanions displacing the NO3^- ions in the gallery. Results from IR and XPS show that the peroxoheteropolyanions structure are well remained. The pillared products showed good catalytic behavior over the cyclohexene conversion. |
