Carbonic anhydrase immobilized on epoxy poss for CO2 capture |
초록 |
Bovine carbonic anhydrase (BCA) was immobilized onto encapsulated epoxy glycidyl POSS-functionalized SiO2 nanoparticles and the product was synthesized and characterized. The enzymatic activities of the free BCA and SiO2/EGPS-conjugated BCA were investigated by hydrolyzing p-nitrophenylacetate (p-NPA), CO2 absorption rate enhanced by BCA on amine based solvents. The CO2 absorption efficiency and reusability of the CA/ SiO2/EGPS were studied after recovered. Storage stability studies suggested that CA/SiO2/EGPS retained nearly 82% of its activity after 20days. Absorbed CO2 was monitored by Ion chromatography, which revealed the quantity of absorbed CO2. The epoxy-immobilized BCA was shown to be an excellent promoter for the absorption of CO2 in amine solvents. |
