The urgency to address global climate change induced by greenhouse gas emissions is increasing. 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 resulted in new generations of CO2 sorbents, which may drive the future of DAC and its large‐scale deployment. This Review describes major types of sorbents designed to capture CO2 from ambient air and they are categorized by the sorption mechanism: physisorption, chemisorption, and moisture‐swing sorption.

“…We compare two different adsorbent-fiber composites: silicon carbide (SiC) fibers impregnated with polyethyleneimine (PEI) and zeolites incorporated into a carbon nanotube (CNT) matrix. Previous work proved the applicability of PEI-impregnation on hollow fibers and the suitability of CNT-based solid sorbents for CO 2 capture [36,37]. Both CNT and SiC feature excellent thermal and chemical stability, and low thermal expansion coefficients.…”

“…available internal surface area are relevant for high adsorption capacities[36]. When testing the adsorption capacities of both impregnation methods with TGA in pure CO 2 , the filtration method yields 21.8 mg g −1 (2.3) at 30 • C whereas the simple impregnation method only exhibits a CO 2 uptake of 8.2 mg g −1 (0.4).…”

Die Dringlichkeit, den durch Treibhausgasemissionen verursachten globalen Klimawandel anzugehen, wächst von Tag zu Tag. Insbesondere der Anstieg der atmosphärischen CO2‐Werte löst Alarm aus. Technologien zum Absorbieren von CO2 aus der Umgebungsluft, oder “Direct Air Capture” (DAC), haben kürzlich gezeigt, dass sie zu “negativen Kohlenstoffemissionen” beitragen können. Die jüngsten Fortschritte in der Oberflächenchemie und der Materialsynthese haben neue Generationen von CO2‐Sorptionsmitteln ermöglicht, die möglicherweise die Zukunft von DAC und seiner großangelegten Verwendung vorantreiben können. In diesem Aufsatz werden die wichtigsten Arten von Sorptionsmitteln zur Gewinnung von CO2 aus der Umgebungsluft beschrieben und nach Sorptionsmechanismen kategorisiert: Physisorption, Chemisorption und Feuchtigkeitswechsel‐Sorption.
