Sujan, A.; Pang, S.; Zhu, G.; Jones, C.; Lively, R. (2019): Direct CO2 capture from air using poly(ethyleneimine)-loaded polymer/silica fiber sorbents. In: ACS Sustainable Chem. Eng. DOI: 10.1021/acssuschemeng.8b06203.
"Direct CO2 capture from atmospheric air is gaining increased attention as one of the most scalable negative carbon approaches available to tackle climate change if coupled with the sequestration of CO2 geologically. [...] In this work, we describe the application of polymer/silica fiber sorbents functionalized with a primary amine rich polymer, poly(ethyleneimine) (PEI), for DAC. Monolithic fiber sorbents composed of cellulose acetate (CA) and SiO2 are synthesized via the dry-jet, wet quench spinning technique."
