From breathing air to flue gas : The cover image illustrates the relationship between the structure of adsorbed carbon dioxide (CO 2 ) on an immobilized amine sorbent and the concentration of CO 2 from breathing air (400 ppm) to simulated flue gas (15 vol %). In situ infrared spectroscopic study determined the structures and fractions of strongly and weakly adsorbed CO 2 on a Class I amine sorbent, which is applicable to CO 2 capture from air to flue gas. Elevating the CO 2 concentration in the stream increased the CO 2 capture capacity, fractions of strongly adsorbed CO 2 , and the binding energy of adsorbed species. Sorbents that capture CO 2 from breathing air can be regenerated by using vacuum regeneration whereas sorbents that capture CO 2 from flue gas have to be regenerated by using a thermal swing process.
