| 摘要: 通过蒸汽诱导内部水解法（VIH）在介孔分子筛SBA-15孔壁上引入Al2O3，合成得到Al2O3@SBA-15复合物，随后与对二苯甲酸配体反应，从而制备得到金属有机框架化合物（MIL-53）与介孔分子筛（SBA-15）复合材料（MIL-53@SBA-15）。采用粉末X射线衍射（PXRD）、N2吸附-脱附测试、扫描电子显微镜（SEM）和透射电子显微镜（TEM）等技术证明成功合成了MIL-53@SBA-15复合材料。染料吸附实验结果表明，MIL-53@SBA-15复合材料相比于SBA-15、MIL-53及其物理混合样品，表现出对丁基罗丹明染料更高效吸附特性。 |

| Abstract: Metal-organic framework@mesoporous composites were obtained via introducing H2BDC into the composite materials Al2O3@SBA-15, which was synthesized through vapor-induced internal hydrolysis (VIH) method. The structure of MIL-53@SBA-15 composites was confirmed by combination of different characterization techniques, such as powder X-ray diffraction (PXRD), N2 adsorption-desorption isotherm test, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Through dye adsorption experiment, MIL-53@SBA-15 compound demonstrated the best adsorptivity performance of butyl rhodamine B dye compared to SBA-15, MIL-53, and physical mixed samples. |
