| Abstract: Layered double hydrotalcites pillared by heteropolyanions, Zn2Al(OH)6-SiW9Z3O40 (here Z=Ti4+, Mo6+) and Zn2Al(OH)6-SiW9Fe3(H2O)3O37 were synthesized by means of direct ionexchange reaction in aqueous solution. XRD and IR show that the gallery heights of interlayer spaces of pillared products are 1.0 nm with the heteropolyanions displacing the NO-3 ions. |
| Keywords: transition element heteropolyanion anionic clay synthesis and characterization |
