Metal polymer complexes methods for carbon dioxide capture

Abstract

Metal polymer complexes and metal polymer complexes adapted for capturing carbon dioxide are disclosed herein. In accordance with one aspect, provided is a metal polymer complex comprising a polymer comprising at least one monomer having an amine group, the polymer complexed with a transition metal selected from nickel, zinc, copper, and a combination of two or more thereof. According to another aspect, provided is a method for capturing carbon dioxide comprising: providing an inlet gas comprising carbon dioxide and water; producing a carbonate, a bicarbonate, a salt thereof, or a combination thereof to remove carbon dioxide from the inlet gas by contacting the inlet gas with a polymer complex substrate; and removing the carbonate, the bicarbonate, the salt thereof, or the combination thereof from the polymer complex substrate by contacting the polymer complex substrate with a regenerant solution comprising water and at least one of a salt or an acid.
