The urgency to address global climate change induced by greenhouse gas emissions is increasing. In particular, the rise in atmospheric CO levels is generating alarm. Technologies to remove CO from ambient air, or "direct air capture" (DAC), have recently demonstrated that they can contribute to "negative carbon emission." Recent advances in surface chemistry and material synthesis have resulted in new generations of CO sorbents, which may drive the future of DAC and its large-scale deployment. This Review describes major types of sorbents designed to capture CO from ambient air and they are categorized by the sorption mechanism: physisorption, chemisorption, and moisture-swing sorption.
应对温室气体排放引发的全球气候变化的紧迫性与日俱增。尤其是大气中一氧化碳（CO）含量的上升引发了人们的警觉。从环境空气中去除CO的技术，即“直接空气捕获”（DAC），最近已证明其有助于实现“负碳排放”。表面化学和材料合成方面的最新进展催生了新一代的CO吸附剂，这可能推动DAC的未来发展及其大规模应用。本综述介绍了旨在从环境空气中捕获CO的主要吸附剂类型，并根据吸附机制对其进行了分类：物理吸附、化学吸附和湿度摆动吸附。
