Abstract

original image

Peptides capture CO2: Poly(L-lysine) brush–mesoporous silica hybrids were prepared and evaluated as biomolecule-based CO2 adsorbents using simulated flue gas (10 % CO2) and simulated ambient air (400 ppm CO2). Compared to representative amine-based adsorbents, the hybrids show higher or comparable capture capacity and outperform other materials in terms of amine efficiency. The hybrids are suggested to be promising new materials for CO2 capture, especially, from ultra-dilute gas streams.
