{[Dy(BTC)(H۲O)]•DMF}n metal organic framework nanoparticles was synthezed through solvthermal method. The product was characterized by XRD, TG, BET, and SEM techniques. SEM images showed that the synthesized sample has semi-cubic particles with average size of ۷۰ nm in length.For improve the gas separation performance,the MOF nano particles were dispersed in polydimethylsiloxane (PDMS) for preparation of mixed matrix membrane (MMM) on support of polyethersulphone (PES). The performance of obtained MMM in separation of NO, N۲ and O۲ gas were investigated, and the effect of MOF nanoparticles (۵, ۱۰, and ۱۵% wt)and feed pressure (۱۰۰-۲۵۰ kPa) on permeability and selectivity were studied. It was found that the membrane performance is evaluated by addition of MOF nano particles in membrane (polymeric matrix), and the feed pressure have not important effect on separation. The performance (NO/N۲ and NO/O۲ selectivity) increased as the loading of MOF particles (up to ۱۵% wt) being dispersed within the polymer matrices.
