View the Complete Application at the US Patent & Trademark Office
A method for capturing CO.sub.2 comprising dissolving at least one pure amino acid (AA) in water without the use of a catalyst for establishing protonation of an amino group of the amino acid, adding at least one base solution to the amino acid and water solution to deprotonate the protonated amino group of the amino acid and forming an amino acid-XOH--H.sub.2O wherein X is sodium or potassium, and subjecting CO.sub.2 to the amino acid-XOH--H.sub.2O to form new nanomaterials is provided. A regenerable nanofiber is disclosed comprising a NaHCO.sub.3 nanofiber, a KHCO.sub.3 nanofiber, or an amino acid nanofiber made from subjecting a CO.sub.2 gas to an amino acid aqueous solvent. Preferably, the amino acid aqueous solvent is one or more of a Gly-NaOH--H.sub.2O, an Ala-NaOH--H.sub.2O, a Phe-NaOH--H.sub.2O, a Gly-KOH--H.sub.2O, an Ala-KOH--H.sub.2O, and a Phe-KOH--H.sub.2O.
