129Xe Nuclear Magnetic Resonance Spectroscopy of Metal–Organic Frameworks

open access: yesAnalysis &Sensing, Volume 6, Issue 4, July 2026.
129Xe NMR spectroscopy is a powerful technique to study porous materials. Properties such as pore sizes, pore connectivity, and dynamic switching processes associated with adsorption can be investigated. With its inertness and highly polarizable electron cloud, Xe allows for sensitive monitoring of small changes in the surface chemistry of materials ...

Theoretical development on the isosteric heat of adsorption and experimental confirmation

open access: yes, 2017
Theoretical framework for the isosteric heat of adsorption is developed treating the effects of the non-ideal gas behavior and the adsorbed phase volume. Rigorous thermodynamic treatment for the adsorbed phase volume is presented for multi-layer adsorption from low to high pressures.

Combining large-scale screening and machine learning to predict the metal-organic frameworks for organosulfurs removal from high-sour natural gas

open access: yesAPL Materials, 2019
High-sour natural gas usually contains organosulfurs besides H2S, the majority of which exist in the form of mercaptans. These impurities of organosulfurs are required to be removed efficiently and economically for commercial application and the ...
