| 摘 要： | 采用水热合成法,通过改变水热晶化条件,制备得到系列MIL-101(Cr)金属-有机骨架材料。XRD、SEM及N2吸附等现代表征结果表明,水热晶化时间和合成体系中反应物浓度会对所得MIL-101(Cr)的结晶度、晶体形貌及孔结构性能产生较大影响。当水热晶化温度为220℃时,最佳晶化时间为8 h,物料n(H2O)∶n(Cr)=370∶1。在此水热晶化条件下所合成的MIL-101(Cr)样品不仅具有更高的结晶度、更大的比表面积和孔体积,以及更为完整的晶体形貌,而且在H2O2氧化环己烷反应中显示出更高的催化活性。

| Abstract: | A series of metal organic framework MIL-101（ Cr） have been successfully synthesized by optimizing hydrothermal crystalline conditions,and were applied to the liquid phase oxidation of cyclohexane with hydrogen peroxide（ H2O2） as oxidant. The characteristic results from XRD,N2adsorption and SEM showed the hydrothermal crystalline time and concentration of Cr species had a great influence on crystallinity,morphology and pore structure properties of resultant MIL-101（ Cr） materials. Among all MIL-101（ Cr） samples,the sample hydrothermally synthesized at 220 ℃ for 8 h with the H2O /Cr molar ratio of370 exhibited the highest crystalline and specific surface area,more complete crystal morphology,and higher catalytic activity for the liquid phase selective oxidation of cyclohexane. |
