摘要: 以硝酸根型水滑石作交换前驱体,通过离子交换法合成了过渡金属离子一、三钛取代的Keggin结构过氧钨硅杂多阴离子柱撑水滑石Zn2Al(OH)6-[SiW11(TiO2)O39]及Zn2Al(OH)6-[SiW9(TiO2)3O37],用元素分析、XRD、IR、XPS、化学分析等手段对产物的组成和结构进行了表征,结果表明,过氧杂多阴离子进入水滑石层间,使水滑石的层间距从0.92nm增加到1.47nm.且过氧杂多阴离子中的基团未被破坏。

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 NO3- ions in the gallery.The results from IR,XPS and chemical analysis show that the structures of peroxoheteropolyanions are well remained.

Key words: Peroxoheteropolyanion, Intercalation, Pillared hydrotalcites
