N2 - Amine-functionalized clover leaf-shaped Al 2O 3 extrudates (CA) were prepared for use as CO 2 sorbent. The as-synthesized materials were characterized by N 2 adsorption, XRD, SEM and elemental analysis followed by testing for CO 2 capture using simulated flue gas containing 15.1% CO 2. The results showed that a significant enhancement in CO 2 uptake was achieved with the introduction of amines into CA materials. A remarkably high volume-based capacity of 70.1mg/mL of sorbent of this hybrid material suggests that it can be potentially used for CO 2 capture from flue gases and other stationary sources, especially those with low CO 2 concentration. The novel adsorbent reported here performed well during prolonged cyclic operations of adsorption-desorption of CO 2.
