Abstract: The present disclosure relates to improved solid state sorbent materials and methods for controlling and enhancing carbon dioxide adsorption performance for selected metal-organic framework (MOF) materials. The present disclosure further relates to inventive methods using a novel class of diamine-appended metal-organic frameworks MOF absorbents displaying step-shaped adsorption isotherms with large carbon dioxide capacities. More specifically, the present disclosure relates to diamine-appended MOF materials exhibiting step-shaped adsorption isotherms that are employed in a method utilizing humidity to control and improve carbon dioxide adsorption performance.

Abstract: This disclosure relates to a select class of porous adsorbent, metal-organic frameworks (MOFs) capable of adsorbing carbon dioxide, their manufacturing, applications, and methods of use. Specifically, this disclosure relates to the solvo(hydro)thermal synthesis of a family of metal-organic frameworks, and their subsequent processing and transformation into material forms suitable for use in acid gas separations. More specifically, this disclosure relates to the preparation and recovery of MOFs at multiple scales of production, demonstrating the suitability and robustness of the materials thus obtained by the disclosed synthetic route and post-synthetic manipulation employed to tailor the materials for use in a variety of commercial acid gas separation systems, with improved performances, recyclability, and reuse characteristics.
