“…The utilization of porous adsorbents for adsorptive separation presents a viable option in terms of energy efficiency and economic viability to capture and purify those F-gases. A variety of functionally specific porous materials containing zeolites, activated carbons, metal–organic frameworks (MOFs), and porous organic cages have been investigated for their potential adsorptive separation applications of F-gases. Among them, MOFs represent an emerging type of functional porous materials that offer distinguished potentials in gas separation due to their diverse structures and precise structural designability, achieved by utilizing various organic linkers and metal corners. Theoretical calculations and experimental investigations have been conducted to explore the adsorption and separation of F-gases utilizing various MOFs, including MOF-74, SBMOF-1, , and HKUST-1. , It is extremely encouraging to thoroughly separate CF 4 /N 2 and SF 6 /N 2 by enhancing the affinity difference between F-gases or N 2 molecules and the designated adsorbent within a host framework-guest molecule. , The majority of studies in this field typically focus solely on examining the single component adsorption isotherm.…”

“…7−9 Therefore, efficient disposal of SF 6 under mild conditions is an important environmental objective. 10 In the past, SF 6 was attempted to be treated by adsorption recovery 11,12 or decomposition. 10,13−17 However, adsorption is not viable for its tedious treatment processes and inefficient adsorbents.…”

“…In the past, SF 6 was attempted to be treated by adsorption recovery , or decomposition. , However, adsorption is not viable for its tedious treatment processes and inefficient adsorbents. Due to its extremely high stability, SF 6 has to be decomposed under harsh conditions, such as high temperatures and pressures.…”
