Abstract

A new strategy for CO 2 capture is reported based on the synergistic effect of electrostatic in-plane and dispersive π–π-stacking interactions of amide and indole with CO 2 . Density functional theory illustrated that the amide group can have an increased ability to capture CO 2 molecules that were just desorbed from an adjacent indole unit. We used this strategy to fabricate a microporous aerogel that exhibited a superior CO 2 capture performance in both dry and wet conditions. The proposed synergistic effect is expected to be a new rationale for the design of CO 2 capture materials.
