Synthesis of Large-Pore Stabilized MIL-53(Al) Compounds with Increased CO2 Adsorption and Decreased Water Adsorption

Abstract

This work reports two large-pore stabilized MIL-53(Al) metal-organic frameworks prepared via solvothermal synthesis strategies that possess no or only slight breathing behaviour. Powder X-ray diffraction confirmed one material remains in the large-pore form under all conditions, while the other material undergoes a more gradual breathing transition than is observed for MIL-53(Al) prepared by traditional methods. Solid-state NMR was employed to elucidate additional structural information and gain insight into the role synthesis solvent plays on breathing behaviour. The CO2 and water adsorption of these large-pore stabilized materials were studied, and the improvement in CO2 loadings over MIL-53(Al) prepared by traditional methods was discussed.
