CO2 Sorbents: New Metrics of Green Sorbents for CO2 Capturing (Adv. Sustainable Syst. 7/2020)

A new classification of green CO2 sorbents, in accordance with green chemistry principles must be developed in order to have low-carbon footprint scrubbing agents in the near future. In article number 1900121, Abdussalam K. Qaroush and co-workers review the use of biomaterials such as chitin, cyclodextrin (CD) (ie, CD-metal–organic frameworks), and ionic liquid based amino acids as potential candidates for CO2 sorbents, with a principle-by-principle analysis of some successful cases in the literature.
