Abstract :Adsorption of N2 on mixed-ligand benzoic acid and 1, 10-phenanthroline ligand of Mninsert ignore into journalissuearticles values(II);  metal-organic framework insert ignore into journalissuearticles values(MOF);–nanoparticles were demonstrated. The synthesized nanostructures are  characterized by techniques such as scanning electron microscopy insert ignore into journalissuearticles values(SEM);, fourier-transform infrared  spectroscopy insert ignore into journalissuearticles values(FT-IR);, and UV-visible spectrophotometry insert ignore into journalissuearticles values(UV-Vis);. The pore size distribution and  adsorption capacity of the synthesized MOF were investigated experimentally by measuring the N2  adsorption isotherm at 77.3 K, and the resulting data were fitted to Brunauer-Emmett-Teller insert ignore into journalissuearticles values(BET);, de  Boer, Dubinin-Radushkevich insert ignore into journalissuearticles values(DR);, Banet-Joyner-Halenda insert ignore into journalissuearticles values(BJH);, Horvath-Kawazoe insert ignore into journalissuearticles values(HK);, and also  applied to Density Functional Theory insert ignore into journalissuearticles values(DFT); models. Excitation of the Mn-MOF nanostructure resulted in  an emission at 400 nm. The DSC study reveals that this molecule has a good chemical stability. The FTIR  measurement shows a variety of functional groups that are highly coordinated. Moreover, the  adsorption properties evaluated by several adsorption models compared with current adsorbent  materials show Mn-MOF has superior thermal stability, a high surface area, and pore openings. Because  of these findings, Mn-MOF appears to be a viable material for storing gases and energy, whether at low  or high pressures.
