| 摘 要： | 将含过渡金属Ni、Co的钨磷杂多化合物引入ZnA1类水滑石中,获得了柱撑化合物,并用XRD、IR等手段对其晶相和内部结构进行了表征。元素分析结果表明,杂多化合物基本符合ZPW11结构。用DTA研究了其热稳定性。这类化合物在异丙醇反应中显示出较强的酸催化性能,完全改变了ZnA1硝酸根型化合物的碱催化活性。

| Abstract: | The Keggin-ionNiPW(11)O(39)(H2O)]5-,CoPW(11)O(39) H2O)]5- intercalated ZnAl hydrotalic-like compounds were prepared. Their crystal structures were characterized by XRD and IR. The result of elementary analysis shows that the products have the composition ratio of ZPW11. Thermal analysis of the compounds was made by DTA. In isopropyl alcohol reaction,the products exhibit the characteristics of strong acidic catalyst while the ZnAl lavered double hydroxide is a typical base catalyst. |
