A method for capturing COcomprising 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&#x2014;HO wherein X is sodium or potassium, and subjecting COto the amino acid-XOH&#x2014;HO to form new nanomaterials is provided. A regenerable nanofiber is disclosed comprising a NaHCOnanofiber, a KHCOnanofiber, or an amino acid nanofiber made from subjecting a COgas to an amino acid aqueous solvent. Preferably, the amino acid aqueous solvent is one or more of a Gly-NaOH&#x2014;HO, an Ala-NaOH&#x2014;HO, a Phe-NaOH&#x2014;HO, a Gly-KOH&#x2014;HO, an Ala-KOH&#x2014;HO, and a Phe-KOH&#x2014;HO.

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

A multilayered cathode for a lithium sulfur battery comprising at least one current collector working electrode having a surface comprising a carbon containing layer, two or more sulfur containing layers wherein at least one of the sulfur layers is located in juxtaposition to and in communication with the carbon containing layer, and at least one outermost layer comprising a positively charged polymer for forming interconnected layers of the sulfur containing layer, the carbon containing layer, and the polymer. Preferably, the cathode has layers that are alternatively arranged of two or more different sulfur containing layers. A lithium sulfur battery is provided and a method of making a multilayered cathode for a lithium sulfur battery is disclosed.

A solid sorbent for the capture and the transport of carbon dioxide gas is provided having at least one first layer of a positively charged material that is polyethylenimine or poly(allylamine hydrochloride), that captures at least a portion of the gas, and at least one second layer of a negatively charged material that is polystyrenesulfonate or poly(acryclic acid), that transports the gas, wherein the second layer of material is in juxtaposition to, attached to, or crosslinked with the first layer for forming at least one bilayer, and a solid substrate support having a porous surface, wherein one or more of the bilayers is/are deposited on the surface of and/or within the solid substrate. A method of preparing and using the solid sorbent is provided.
