Figure 13. (A) Single-component CO₂ isotherms on ZnDatzBdc up to 100 kPa and varied temperatures; (B) adsorption isotherms of CO₂, N₂, and CH₄ up to 100 kPa at 273 and 298 K; (C) CO₂ working capacities for the step-shaped isotherm of ZnDatzBdc and the simulated Langmuir isotherm from the CO₂ adsorption data in the open phase, for a cycle of adsorption at 100 kPa and desorption at 20 kPa (273 K); (D) comparison of CO₂ uptakes and working capacities of ZnDatzBdc and other flexible MOFs with S-shaped CO₂ isotherms.
