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.
