摘要
利用离子液体具有良好相容性的特点,对金属有机框架UiO-66-NH_(2)进行合成后修饰。通过微波辐射辅助法合成了金属有机框架材料UiO-66-NH_(2),并对其进行修饰合成了[HOOCMMIm]Br@UiO-66-NH_(2),产率达65%。对其进行表面形貌观察,离子液体修饰的[HOOCMMIm]Br@UiO-66-NH_(2)骨架材料较UiO-66-NH_(2)粒径变大;X射线衍射表征显示,修饰后的[HOOCMMIm]Br@UiO-66-NH_(2)仍保持原有骨架结构;在77K时氮气物理吸附测试结果表明,比表面积较UiO-66-NH_(2)提高了46.4%,孔体积增大了49.3%。
The metal-organic framework(MOF)UiO-66-NH_(2) was post-synthetically modified by taking advantage of the characteristics of good compatibility of ionic liquids.The MOF UiO-66-NH_(2) was synthesized by microwave radiation-assisted method and modified to synthesize[HOOCMMIm]Br@UiO-66-NH_(2) in 65%yield.The surface morphology was observed,and the ionic liquid modified[HOOCMMIm]Br@UiO-66-NH_(2) skeleton material became larger in size than UiO-66-NH_(2).XRD characterization showed that the modified[HOOCMMIm]Br@UiO-66-NH_(2) still kept the original skeleton structure.The results of nitrogen physisorption test at 77 K showed that the specific surface area increased by 46.4%and the pore volume increased by 49.3%compared with that of UiO-66-NH_(2).
