Preparation of Ni-metal organic framework-74 nanospheres by hydrothermal method for SO2 gas adsorption

In this investigation hierarchical nanospheres-like Ni-MOFs were successfully synthesized with hydrothermal method. These MOFs samples were characterized with electron microscopy (SEM and TEM) for crystal structure, X-ray diffraction for phase structure, and nitrogen adsorption (BET) for pore textural properties. The experimental results showed that Ni-MOF samples synthesized by the hydrothermal method had a smaller particle size with relatively more uniform particle size distribution. Based on high roughness, crystallinity, and unreported type of FTIR spectrum, a new structure of Ni-MOF structure was proposed.
