摘要：

In this study, we have focused on the intercalation by ion-exchange of some polyoxovanadate anions from aqueous solution (decavanadate V10O286-, tetravanadate V4O124-, and pyrovanadate V2O74-) into the layers of a copper chromium hydrotalcite-like compound. PXRD, FTIR, TGA, and EXAFS studies have provided information about the specific oxovanadate ions in the interlayers and their orientation. Thermal treatment of these LDHs was also examined. A grafting process of pyrovanadate anions onto the hydroxylated sheets has been demonstrated at room temperature. (C) 1996 Academic Press, Inc.
