Figure 5. Separate ability of PAF-1-NH2. (A) CO2/N2 selectivity of PAF-1 and PAF-1-NH2; (B) CO2/N2 selectivity and CO2 Qst comparison with other POPs; (C) CO2 cycles adsorption of PAF-1-NH2; (D) Breakthrough curves of PAF-1-NH2 for a CO2/N2 (15:85, v/v) gas mixture with a total flow of 10 mL·min-1 at 298 K and 1 bar. PAF-1: Porous aromatic framework-1; POPs: porous organic polymers.
