Sorbenten zur direkten Gewinnung von CO 2 aus der Umgebungsluft

: The urgency to address global climate change induced by greenhouse gas emissions is growing. In particular, the rise in atmospheric CO2 levels is generating alarm. Technologies to remove CO2 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 enabled new generations of CO2 sorbents, which may drive the future of DAC and its large-scale deployment. This paper reviews major types of sorbents designed to capture CO2 from ambient air, which are categorized by sorption mechanism: physisorption, chemisorption, and moisture-swing sorption.
