用离子交换法合成了杂多阴离子柱撑阴离子粘土ＺｎＡｌ-ＳｉＷ１１和ＺｎＡｌ-ＳｉＷ１１Ｚ（Ｚ＝Ｃｏ２＋，Ｎｉ２＋，Ｃｕ２＋）．ＸＲＤ和ＩＲ测定结果表明，这些层柱化合物的通道高度是１．４６×１０-７ｃｍ，层间阴离子保持它们的Ｋｅｇｇｉｎ结构．它们在空气中热分解序列为：ＺｎＡｌ-ＳｉＷ１１Ｎｉ（３４７℃）＞ＺｎＡｌ-ＳｉＷ１１Ｃｏ（３４１℃）＞ＺｎＡｌ-ＳｉＷ１１Ｃｕ（３３５℃）＞ＺｎＡｌ-ＳｉＷ１１（３２９℃）＞ＺｎＡｌ-（２９０℃），在沸腾水溶液中稳定存在的ｐＨ值范围是３．６～７．５．
The heteropolyanion pillared anion clay ZnAl-SiW11 and ZnAl-SiW11Z (Z = Co2 +, Ni2 +, Cu2 +) were synthesized by ion exchange method. The XRD and IR results show that the channel height of these pillared compounds is 1.46 × 10-7 cm, and the interlayer anions keep their Keggin structure. Their thermal decomposition sequences in air are: ZnAl-SiW11Ni (347 ℃)> ZnAl-SiW11Co (341 ℃)> ZnAl-SiW11Cu (335 ℃)> ZnAl- SiW11 (329 ℃)> ZnAl- (290 ℃) Stable pH range of aqueous solution is 3.6 ~ 7.5.
