“…The separation selectivities of JLU-MOF110(FeNi) and JLU-MOF110(Fe) are similar at 298 K. The selectivities of JLU-MOF110(FeNi) at 1 bar are S = 10.1 (CO 2 /CH 4 = 0.5/0.5) and 9.7 (CO 2 /CH 4 = 0.05/0.95). The selectivity of CO 2 /CH 4 for JLU-MOF110(FeNi) is higher than that of Zn-MOF 1 ( S = 6.8), SNNU-325 ( S = 4.0), 1-Eu-a ( S = 5.4), ZJNU-19 ( S = 6.4), and MFM-102-NO 2 ( S = 5.0) . The detailed CO 2 /CH 4 selectivity comparisons for the recently reported MOF materials are listed in Table S6.…”

Based on the hard-soft acid base (HSAB) theory, three robust isoreticular metal−organic frameworks (MOFs) with nia topology were successfully synthesized by solvothermal reaction, and [Fe 2 NiO(BHB)-(H 2 O) 3 ] (JLU-MOF110(FeNi)) (DMA = N,N-dimethylacetamide, H 6 BHB = 4,4″-benzene-1,3,5-triyl-hexabenzoic acid)}. Both JLU-MOF110(In) and JLU-MOF110(Fe) are cationic frameworks, and their BET surface areas are 301 and 446 m 2 /g, respectively. By modification of the components of metal clusters, JLU-MOF110(FeNi) features a neutral framework, and the BET surface area is increased up to 808 m 2 /g. All three MOF materials exhibit high chemical and thermal stability. JLU-MOF110(In) remains stable for 24 h at pH values ranging from 1 to 11, while JLU-MOF110(Fe) and JLU-MOF110(FeNi) persist to be stable for 24 h at pH from 1 to 12. JLU-MOF110(In) exhibits thermal stability up to 350 °C, whereas JLU-MOF110(Fe) and JLU-MOF(FeNi) can be stable up to 300 °C. Thanks to the microporous cage-based structure and abundant open metal sites, JLU-MOF110(In), JLU-MOF110(Fe), and JLU-MOF110(FeNi) have excellent CO 2 capture capacity (28.0, 51.5, and 99.6 cm 3 /g, respectively, under 298 K and 1 bar). Interestingly, the ideal adsorption solution theory results show that all three MOFs exhibit high separation selectivity toward CO 2 over N 2 (35.2, 43.2, and 43.2 for CO 2 /N 2 = 0.15/0.85) and CO 2 over CH 4 (14.4, 11.5, and 10.1 for CO 2 /CH 4 = 0.5/0.5) at 298 K and 1 bar. Thus, all three MOFs are potential candidates for CO 2 capture and separation. Among them, JLU-MOF110(FeNi) displays the best separation potential, as revealed by dynamic column breakthrough experiments.
