Title: Amino acids react with carbon dioxide (CO2) and form nanofibers and nanoflowers

Abstract

A method for capturing CO2 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—H2O wherein X is sodium or potassium, and subjecting CO2 to the amino acid-XOH—H2O to form new nanomaterials is provided. A regenerable nanofiber is disclosed comprising a NaHCO3 nanofiber, a KHCO3 nanofiber, or an amino acid nanofiber made from subjecting a CO2 gas to an amino acid aqueous solvent. Preferably, the amino acid aqueous solvent is one or more of a Gly-NaOH—H2O, an Ala-NaOH—H2O, a Phe-NaOH—H2O, a Gly-KOH—H2O, an Ala-KOH—H2O, and a Phe-KOH—H2O.
