| Abstract: | Metal organic framework（MOF-5） nanoparticles were synthesized via diffusion of triethlyamine （TEA） into the solution of 1, 4-Benzenedicarboxylic acid （H2BDC） and Zn（NO3）2·6H20 at room temperature. Through controlling the addition amount of water into the reaction system, different morphological nanoparticles were obtained. The scanning electron microscopy （SEM） measurement indicated that the sample of MNMOF-6 showed particle-like morphology with the diameter of 50-100 nm. And the sample of MNMOF- 7, MNMOF-8 and MNMOF-9 showed the morphology of rod, needle and belt, respectively. The N2 adsorption measurements for the MOF-5 nanoparticles were carried out at 77K. |
