| 摘 要： | 采用共沉淀法制备Mg-Al-LDHs,并以Mg-Al-LDHs为前体,采用返混沉淀法进行插层组装合成马来酸根离子柱撑水滑石。采用傅里叶红外光谱、X射线衍射、差热分析对其进行了表征。结果表明,马来酸根离子可以插入Mg-Al水滑石层间,其层间距由0.76nm增大到1.10nm,形成具有超分子结构的马来酸根柱撑水滑石,达到纳米尺寸;给出了分子结构模型;其热稳定性能提高。

| Abstract: | Mg-Al Layered Double Hydroxides(Mg-Al-LDHs) have unique structural memory effect.Used it as front body, maleate anions were inserted into layers by back mixing precipitation method.The maleic acid anions column pillared hydrotalcites were synthesized.The samples prepared were characterized by X-Ray Diffraction(XRD), Fourier transform infrared(FTIR) and Differential Thermal Analysis(DTA).The results show that the initial interlayer carbonate ions can be completely replaced by the maleic acid anions under con... |
