【摘要】 采用水热合成及离子交换法将Keggin结构三铁九钨镓酸盐杂多阴离子GaW9Fe3（H2O）3嵌入Zn2Al型阴离子粘土层间，得到了新型层柱状微孔材料Zn2Al－GaW9Fe3．用元素分析、XRD、IR、XPS等手段对产物的组成和结构进行了表征．结果表明，杂多阴离子嵌入Zn2Al型阴离子粘土层间，使柱撑杂多阴离子粘土具有1．0nm的通道高度．更多还原

【Abstract】 Layered double hydrotalcites pillared by heteropolyoxometates,Zn2Al-GaW9Fe3was synthesized via hydrothermal reaction and anion exchange,and was characterized by ele- mental analysis,XRD,IR and XPS.The result shows that the gallery height of layered dou- ble hydrotalcites pillared by heteropolyanion is 1.0nm.更多还原
