通过热分解酸性层状双氢氧化物（LDH）[Zn0.67·Al0.33（OH）2]（CO 3）1.17·0.33H2O制备的无定形锌铝氧化物固溶体（Zn0.67Al0.33O1.17）被发现与Keggin样杂多酸盐阴离子如α-[Si·W11 O39]8-和α-1，2，3-[SiV 3 W 9 O 40]7-在酸性溶液中反应，形成层柱LDH结构，层柱高度为9.9 A。
An amorphous zinc-aluminium oxide solid solution, Zn0.67Al0.33O1.17, Prepared by the thermal decomposition of the acidic layered double hydroxide (LDH), [Zn0.67·Al0.33(OH)2](CO3)1.17·0.33H2O, was found to react with Keggin-like heteropolyoxometalate anions such as α-[Si·W11O39]8− and α-1,2,3-[SiV3W9O40]7− in acid solution to form pillared LDH structures with gallery heights of 9.9 A.
