| 摘 要： | 采用共沉淀法制备纳米Mg-Al-LDHs水滑石,并以纳米Mg-Al水滑石为前体,采用返混沉淀法进行插层组装,合成酒石酸根阴离子柱撑水滑石。采用红外光谱、X射线衍射对样品进行了表征。结果表明,酒石酸根阴离子可以插入纳米Mg-Al水滑石层间,完全取代CO32-,形成具有超分子结构的稳定酸根阴离子柱撑水滑石,其尺寸达到纳米级。

| Abstract: | Mg-Al layered double hydroxides were prepared with co-precipitation method,when the tartaric acid column pillared hydrotalcites were synthesized by eturns mixes the precipitation method with Mg-Al-CO23 precursor layered double hydroxides(LDHs).The samples prepared were characterized by XRD,FTIR.The results show that the initial interlayer carbonate ions can be completely replaced by the tartaric acid anion under controlled conditions,and they have nanometer size. |
