摘要
在对苯二甲酸(H2BDC)苯环上引入不同的取代基,通过与氯化锆(ZrCl4)和冰乙酸在N,N-二甲基甲酰胺(DMF)中进行溶剂热反应合成UiO-66系列金属有机骨架材料,测试材料对合成气中CO2,CO的吸附性能。结果表明UiO-66-NH2对CO2吸附量最高,为100.14cm3/g,对CO吸附量为17.69cm3/g,在CO2/CO体系中对CO2有较高的分离性能。
UiO-66 series metal-organic frameworks(MOF)were synthesized with zirconium chloride(ZrCl4)and 1,4-benzenedicarboxylic acid(H2BDC)which different functional groups were employed in hydrothermal condition modified by acetic acid in dimethyl formamide(DMF)solution.The CO2 and CO sorption was tested which indicated that the highest uptake of CO2 belonged to UiO-66-NH2 which the corresponding value was 100.14 cm3/g,otherwise the uptake of CO was 17.69 cm3/g,which had good adsorption property for CO2.
