Abstract: The Keggin-ion[NiPW11O39(H2O)]5-,[CoPW11O39 H2O)]5- intercalated ZnAl hydrotalic-like compounds were prepared.Their crystal structures were characterized by XRDand 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.

Key words: Heteropolycompound, Isopropyl alcohol reaction, Layer-type compound
