Abstract: A polymer composite includes a polymer substrate, activated carbon, and a carbonate salt. The activated carbon is infused with the carbonate salt. A hybrid composite includes a fibrous mat with activated carbon and potassium carbonate crystals adhered to the fibrous mat. Making a polymer composite includes combining activated carbon with a polymer to yield a mixture, and electrospinning the mixture to yield nanofibers, wherein the carbonate salt is adhered to or embedded in the nanofibers. Capturing carbon dioxide from a quantity of air includes contacting the polymer composite with the quantity of air in the presence of water vapor to yield potassium bicarbonate sorbed on the polymer composite.

Abstract: Embodiments of the invention a method for producing a composite paper by providing a particulate sorbent, providing a paper pulp, and mixing the particulate sorbent and the paper pulp to develop a mixture. The method includes producing an article from the mixture that includes the particulate sorbent at least partially distributed through at least a portion of the article. Further, the at least one article is configured and arranged to uptake and release carbon dioxide as a function of moisture content. Some embodiments of the invention include a composite paper-like assembly including at least a first and second layer including hydrophobic fibers, and sorbent particles and/or a sorbent loaded paper sandwiched between the first and second porous sheets. Some further embodiments include a method for producing a material that supports a moisture swing by providing a material including activated carbon, and infusing the activated carbon with ionic salt.

Abstract: A carbon dioxide capture and release method of forming a MOF matrix material including at least one metal-organic-framework crystal that includes at least one metal ion or metal ion cluster coordinated to polydentate organic ligands. The method includes forming a positive moisture swing CO2 host by application of at least a portion of the MOF matrix material to at least a portion of a good, and exposing the good to a feed gas. The method also includes altering the absorption and desorption of CO2 in the CO2 host through a swing absorption/desorption process of moisture content, where an equilibrium pressure of CO2 over the CO2 host is based at least in part on the moisture content. The metal-organic-framework crystal can be UIO-66 including Zr6O4(OH)4(CO2)12 clusters linked by terephthalate acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by amino-terephthalic acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by nitro-terephthalic acid ligands.
