Abstract: A system and method for passive collection of atmospheric carbon dioxide is disclosed. The system includes a harvest chamber having a first opening and a sorbent regeneration system. The system also includes a capture body coupled to and movable by a support structure. The capture body includes a sorbent material and is movable by the support structure to be in a collection configuration wherein at least a portion of the capture body is in contact with a natural airflow outside the harvest chamber such that atmospheric carbon dioxide is captured by the sorbent material, and a release configuration wherein at least a portion of the capture body holding captured carbon dioxide is operated upon by the regeneration system inside the harvest chamber such that captured carbon dioxide is released to form an enriched gas.

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 method for enhancing a sorbent membrane for carbon dioxide capture is disclosed. The method includes applying a layer of a hydrophobic material to at least one surface of the sorbent membrane. The hydrophobic material may be one of a polysioxane, a silicone compound, and a fluoroacrylic copolymer. The sorbent membrane may be an anionic exchange membrane, and may have a quaternary ammonium functional group. The layer of hydrophobic material reduces the amount of water used in the carbon dioxide capture process, and relaxes the water quality constraints.

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.

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.
