The "on-demand" capture and utilization of CO 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 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 capture and conversion (ICCC) strategy has been fully elucidated mechanistically via dedicated computational, spectroscopic and thermal analyses.
通过一种易于获取的双功能有机复合材料有效地实现了对一氧化碳的“按需”捕获和利用。氧化石墨烯（GO）表面与天然存在的精氨酸进行共价和可控衍生化，得到了一种“智能”材料，该材料能够从高纯度烟道气以及低浓度气流（即直接空气捕获）中捕获（化学吸附）一氧化碳，并伴随化学活化以纳入环状碳酸酯。通过专门的计算、光谱和热分析，从机理上充分阐明了整体集成的一氧化碳捕获与转化（ICCC）策略。
