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. |
