Abstract
Abstract The “on‐demand” capture and utilization of CO 2 is effectively realized with a readily accessible dual function organic composite. The covalent and controlled derivatization of graphene oxide (GO) surface with naturally occurring arginine led to a “smart” material capable of capturing (chemisorption) CO 2 from high‐purity flue‐gas as well as low‐concentration streams ( i. e . direct air capture) and concomitant chemical activation toward the incorporation into cyclic carbonates. The overall integrated CO 2 capture and conversion (ICCC) strategy has been fully elucidated mechanistically via dedicated computational, spectroscopic and thermal analyses.
