| Abstract: | Pillared layered double hydroxides(LDH),Zn2Al(OH)6-SiW11(TiO2)O39 and Zn2Al(OH)6-SiW9(TiO2)3O37 were synthesized by direct ion-exchange reaction in aqueous solution,and characterized by elementary analysis,XRD,IR and XPS spectra.The interlayer spaces of the pillared products increase from 0.92 nm to 1.47 nm with the peroxoheteropolyanions displacing the ions in the gallery.The results from IR,XPS and chemical analysis show that the structures of peroxoheteropolyanions are well remained. |
