文摘

A microporous MOF Zn(BDC)(4,4'-Bipy)_0.5 (MOF-508b, BDC = 1,4-benzenedicarboxylate, 4,4'-Bipy = 4,4'-bipyridine) was examined for the separation and removal of CO₂ from its binary CO₂/N₂ and CO₂/CH₄ andternary CO₂/CH₄/N₂ mixtures by fixed-bed adsorption. With one-dimensional pores of about 4.0 × 4.0 Å toinduce their differential interactions with the three components, MOF-508b exhibits highly selective adsorptionto CO₂ with the adsorption capacity of 26.0 wt % at 303 K and 4.5 bar. This is the first example of microporousMOFs for the separation and removal of CO₂ from its binary and ternary mixtures by fixed-bed adsorption,establishing the feasibility of the emerging microporous MOFs for their potential applications in this veryimportant industrial and environmental process.
