摘要
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.
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 02.
