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: Some embodiments include a method of preparing a phototuned metal-organic framework by forming a first solution by dissolving ZrOCl2.8H2O in dimethylformamide (DMF) and formic acid, mixing and dissolving 1,4-phenylenediacrylic acid in a second solution of dimethylformamide (DMF) and trimethylamine, and at least partially mixing the first and second solutions to form a mixture. The method further includes sealing the mixture in an autoclave and heating the mixture to above ambient temperature for a specified period of time to prepare ZrPDA metal-organic framework, and extracting the ZrPDA metal-organic framework and at least partially reacting to a specified degree at least some of ZrPDA metal-organic framework through [2+2] cycloaddition reactions. The specified degree can be tunable based at least in part on at least one of the intensity of UV radiation, the exposure time, and the UV wavelength.
