摘　　要：通过溶剂热法制备了较高比表面积的锌基金属有机骨架(MOF-5)和经乙二胺(ethylenediamine,EDA)改性的功能化锌基金属有机骨架材料(EDA/MOF-5),利用XRD、FT-IR、SEM和TG等对其结构与性能进行了表征,并探讨了其对刚果红染料的吸附性能。结果表明,成功制备MOF-5和EDA/MOF-5。通过SEM可以看出,乙二胺的加入使MOF-5的形貌结构发生了变化;由TG谱图知,EDA/MOF-5的热稳定性较MOF-5变化不大;EDA/MOF-5的吸附性能较MOF-5明显增大。In this study,the organic framework of zinc base metal with higher specific surface area(MOF-5)and functional zinc base metal organic matrix materials(EDA/MOF-5)modified by ethylenediamine(EDA)were prepared by hydrothermal method.The structure and properties were characterized by using XRD,FT-IR,SEM and TG,and the adsorption properties of Congo red dyes were discussed.The results showed that MOF-5and EDA/MOF-5were successfully prepared.It can be seen from SEM that the addition of ethylenediamine has changed the morphology structure of MOF-5.The thermal stability of EDA/MOF-5is similar with MOF-5.The adsorption performance of EDA/MOF-5was significantly higher than that of MOF-5.
