摘    要:首先采用一定方法合成了水滑石锌铝碳酸根双氢氧化物(Zn2A l-CO3-LDHs)及镁铝碳酸根双氢氧化物(Mg2A l-CO3-LDHs),并通过用粉末X射线衍射(XRD)、红外光谱(IR)等手段对产物的结构进行了表征。接着以水滑石锌铝碳酸根双氢氧化物(Zn2A l-CO3-LDHs)及镁铝碳酸根双氢氧化物(Mg2A l-CO3-LDHs)为前体,以乙二醇为介质,用离子交换法制备了柠檬酸柱撑层状双氢氧化物(Zn2A l-C6H7O7-LDHs和Mg2A l-C6H7O7-LDHs),并用粉末X射线衍射(XRD)、红外光谱(IR)等测试技术对样品进行了表征。结果表明,C6H7O7-可以完全取代水滑石层间的CO32-柱撑水滑石具有良好的层状结构。

关 键 词:水滑石  柱撑水滑石  柠檬酸  制备  结构表征
