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.

Docking of CuI and AgI in Metal-Organic Frameworks for Adsorption and Separation of Xenon

Haoze Wang et al.

Summary: In this study, a metal docking strategy was introduced using the spatial arrangement of organic struts in a MOF. The resulting metalated MOFs showed high capacity and selectivity for Xe adsorption, with Ag-MOF-303 exhibiting exceptional performance. Coordination geometries of Cu-I and Ag-I were examined using advanced spectroscopy techniques.

Linker Desymmetrization: Access to a Series of Rare-Earth Tetracarboxylate Frameworks with Eight-Connected Hexanuclear Nodes

Xiu-Liang Lv et al.

Summary: This study investigates the influence of different sizes, rigidities, and symmetries of linkers on the formation of RE-tetracarboxylate MOFs and highlights the critical role of linker desymmetrization in constructing RE-MOFs. By rational linker design, MOF materials with different topologies can be obtained, which is important for separation and catalysis applications.

A robust metal-organic framework showing two distinct pores for effective separation of xenon and krypton

Li Wang et al.

Summary: In this study, a new robust MOF (ECUT-51) with two different sizes of pores (pore A and pore B) exhibited excellent Xe/Kr separation ability, as demonstrated by dynamic breakthrough experiments. Insights into the separation mechanism were obtained through Grand Canonical Monte Carlo (GCMC) simulation and Density Functional Theory (DFT) calculation, revealing the accommodation of both Xe and Kr in pore A but the prohibitive nature of Kr in pore B.
