Goeppert, A.; Zhang, H.; Sen, R.; Dang, H.; Prakash, S. (2019): Efficient, stable, oxidation resistant and cost effective epoxide modified polyamine adsorbents for CO2 capture from various sources including air. In: ChemSusChem. DOI: 10.1002/cssc.201802978.
„Carbon dioxide adsorbents based on the reaction of pentaethylenehaxamine (PEHA) or tetraethylenepentamine (TEPA) with propylene oxide (PO) were easily prepared in “one pot” by impregnation on a silica support in water. The starting materials are readily available and have a low cost facilitating the production of the adsorbents on a large scale. The prepared polyamine/epoxide adsorbents were efficient in capturing CO2 and regenerable under mild conditions (50‐85 °C).“
