More Information
Summary:This disclosure describes the synthesis of layered double hydroxide compositions interlayered by polyoxometalate anions with Keggin-type structures and having the formula [M1-xllMxlll(OH)2]Ax/nn-.yH2O, wherein, Mll is a divalent metal and Mlll is a trivalent metal, A is an anionic polyoxometalate of negative charge n, x range between 0.12 to 0.8, and y is a positive number. The products exhibit well-defined XRD peaks corresponding to uniformly crystalline layered products with basal spacing values>/=14 ANGSTROM .
