Fig. 5: Experimental breakthrough experiments.

Experimental column breakthrough curves at 298 K for: Zn-fa-datz (1) powder using a mixture of (a) C2H2/C2H4/C2H6/He (1:1:1:4, total gas pressure of 1 bar, total flowing rate of 3.5 mL/min), and an equimolar mixture of (b) CO2/C2H2/C2H4/C2H6 (1:1:1:1, total gas pressure of 1 bar, total flowing rate of 2 mL/min). Zn-fa-atz (2) powder using (c) C2H2/C2H4/C2H6/He (1:1:1:4) and (d) CO2/C2H2/C2H4/C2H6 (1:1:1:1). Color code: Zn, purple; C, gray; O, red; N, blue; H, white.
