Amine-functionalized MIL-53(Al) for CO2/N2 separation: Effect of textural properties

► A high-quality amino-MIL-53(Al) was synthesized by a solvothermal method in DMF. ► Breathing behavior of CO2 and N2 was affected by the textural properties of the amino-MIL-53(Al). ► Repeated high pressure cyclic test showed no deterioration in the CO2 adsorption capacity.
