HIGH PERFORMANCE CO2 ADSORBENTS MADE FROM NATURAL SILK
WARF: P250140US01

Inventors: Bu Wang, Md Sariful Sheikh


The Invention

UW-Madison researchers have developed a solid amino acid-based CO2 adsorbent based on silk fibroin. Silk fibroin is a natural blend of various amino acids that is organized into a structure with a high surface area that can effectively adsorb CO2. Silk nano-fibroin synthesized from the bombyx mori (silk moth) cocoon has a very high CO2 adsorption capacity that is substantially higher than that of state-of-the-art amino acids, amino acid ionic liquids, zeolite, metal organic frameworks (MOFs), etc. It also has a low heat of adsorption and can be regenerated at low temperature. Finally, it demonstrates high thermal stability and promising cyclic operation stability.
