Abstract

We have systematically synthesized a series of functionalized UiO-66-X (X = NO₂, NH₂, Cl, Br, I, Br₂) compounds to further improve the selective SF₆ adsorption of UiO-66, which is one of the best-performing adsorbents, and to investigate the effect of the polarizability of adsorbent atoms on the SF₆ and CF₄ adsorption, especially at low pressures, which is the industrially relevant condition. UiO-66-Br₂ with the highest polarizability exhibited a high Henry's constant (104 mmol g⁻¹ bar⁻¹) for SF₆ adsorption as well as high SF₆/N₂ selectivity (2 0 0), both of which are considerably higher than those of other adsorbent materials, including MOFs. Moreover, UiO-66-Br₂ showed good SF₆/N₂ separation under a dynamic mixture flow condition as well as facile regeneration without increasing the temperature. These results show that UiO-66-Br₂ is a potential adsorbent for the selective capture of SF₆ from various SF₆/N₂ mixtures in industry.
