Robust and Radiation-Resistant Hofmann-Type Metal-Organic Frameworks for Record Xenon/Krypton Separation

Jiyan Pei et al.

Summary: This paper reports on the discovery of two robust and radiation-resistant MOFs with adjacent metal sites and perfect pore sizes that can efficiently separate xenon from krypton. These materials exhibit record-high xenon uptake capacities and selectivities, and the locations of xenon molecules within one of the MOFs were visualized using single-crystal X-ray diffraction.

Creating Optimal Pockets in a Clathrochelate-Based Metal-Organic Framework for Gas Adsorption and Separation: Experimental and Computational Studies

Wei Gong et al.

Summary: In this work, a highly porous and robust metal-organic framework (MOF) called NU-200 was successfully designed and synthesized. Computational simulations showed that the hierarchical bowl-shaped nanopockets in NU-200 played a crucial role in enhancing the affinity for xenon. The unique pocket confinement effect was validated using a similarly sized probe, sulfur dioxide.

Construction of an Anion-Pillared MOF Database and the Screening of MOFs Suitable for Xe/Kr Separation

Chenkai Gu et al.

Summary: The separation of xenon/krypton mixtures is challenge due to low selectivity in porous materials. Anion-pillared MOFs show potential in gas separations, with heterogeneity of fluorine groups possibly enhancing Xe working capacity without reducing selectivity. SIFSIX-6-Cd-i is predicted to perform better for Xe/Kr separations than previously reported MOFs.

Tailoring Pore Structure and Morphologies in Covalent Organic Frameworks for Xe/Kr Capture and Separation

Yuan Mengjia et al.

Summary: This study synthesized two-dimensional COF materials with different pore properties to investigate their adsorption of Xe and Kr. The results showed that COF materials with narrower pore apertures and higher porosity are more conducive to capturing Xe and Kr. Furthermore, based on adsorption heat and selectivity studies, ATFG-COF exhibited high selectivity for Xe and Kr adsorption.
