a) Single-component adsorption isotherms of C2H4 (red) and C2H6 (blue) in Co-gallate at 298 K in the pressure range of 0–1 bar. Empty symbols represent desorption data. b) Comparison of IAST selectivities for equimolar C2H4/C2H6 mixtures in M-gallate with other best-performing materials in the range of 0–1 bar. The adsorption isotherms were collected at 318 K for FeMOF-74,[10a] 298 K for M-gallate, MgMOF-74[9a] and zeolite 13X,[21] 296 K for CoMOF-74,[22] 293 K for NOTT-300,[23] and 283 K for zeolite 5A.[24] c) Comparison of C2H4/C2H6 adsorption selectivity and volumetric C2H4 uptake at 1 bar in M-gallate and other best-performing materials. d) Experimental breakthrough curves of M-gallate for the equimolar C2H4/C2H6 mixture at 273 K and 1 bar with a constant flow rate of 0.5 mLmin−1.
