Abstract Recently, we are dealing with the problem of treating Xe / Kr gas which is a volatile radionuclide material generated in spent fuel pre-treatment process. In this study, we have developed a separation adsorbent material capable of separating Xe / Kr gas with high selectivity at room temperature by combining porous metal organic structure optimized for gas separation and metal nanoparticles. The MOFs(Metal-organic frameworks) used in this study was synthesized by introducing Ag nanoparticle, which can increase adsorption selectivity of Xe gas, and synthesizing UiO66 based on Zr. UiO66 was partially fluorinated, which can increase Kr gas adsorption selectivity, FUiO66 was also synthesized. The partially fluorinated FMOFCu was also synthesized from N,N-dimethylformamide instead of Deionized water. BET analysis of the synthesized materials showed that Xe / Kr gas can be separated with high selectivity at room temperature.
