采用水热合成法制备MOF-5晶体,实验结果表明以二甲基甲酰胺为溶剂,Zn2+/对苯二酸摩尔配比为2.7的混合液在130°C下水热反应4 h可得到规则的立方体结构的MOF-5晶体.XRD和FTIR表明制备的晶体为MOF-5晶体,且以桥式单氧单齿型配位模式.MOF-5具有较好的吸附N2的性能,但是在有氧气存在条件下会干扰N2的吸附.
Abstract：Metal organic framework materials(MOFs-5) were synthesized using N,N-dimethylformamide as solvent by hydrothermal method,and the hydrothermal reaction was carried out 130℃ for 4 hours.The optimal molar radio of Zn2+/ terephthalic acid is 2.7.SEM and XRD analysis results show that the MOF-5 exhibit a cubic crystal structure and the characteristics of MOF-5 peaks.The MOF-5 also exhibits excellent adsorption of N2,and the absorption rate can be controlled by O2.
