摘要
以Mg(OH)2和NaAlO2为原料,采用新原料路线共沉淀法实现了柠檬酸根插层结构LDHs的超分子组装。用XRD、FT-IRTG-DTA和元素分析等手段对样品进行分析表征。结果表明,新原料路线共沉淀法较常用的共沉淀法得到的柠檬酸根插LDHs结晶度高、晶相单一,客体柠檬酸根在LDHs层间的排列高度有序。
Citrate-pillared LDHs with supramolecular structure has been successfully assembled by a new synthesis method using Mg (OH)(2) and NaAlO2 as raw materials. The supramolecular structure of citrate-pillared LDHs was characterized by XRD, FT-IR, TG-DTA and the composition was analyzed by ICP. The structure model was established based on the results of characterization and analyses. It is shown that highly crystallized citrate-pillared LDHs has been prepared in comparison with the conventional coprecipitation method.
