In the case of type-A zeolites, the channel size will be reduced from 0.42 nm down to 0.3 nm when Ca2+ is ion-exchanged into K+. In addition to the changes to the cationic property of the zeolites, the Si/Al ratio can be varied to change the acidity of the zeolites. The Si/Al ...
In the literature, absolute, excess, and total adsorption terms are generally used to describe CH4 adsorption in a MOF adsorbent. CH4 adsorption in MOFs is driven by the interplay of the weak dispersive forces between gas molecules and the adsorbent. The distance between adsorbates and surface of...
Another property is the porosity, defined as the ratio of the void volume to the total volume of voids and solids. Such mesoporous materials are ubiquitous in industrial catalysis and separation processes, such as pressure-swing adsorption, chromatography, and membrane separation. The principal reason...
Adsorption is a major industrial separation technique for the purification of effluent media. It is a mass transfer operation through which a solid material can selectively remove dissolved components from an aqueous solution by attracting the dissolved solute to its surface. Therefore, it involves the...
This provides a novel method for the synthesis of complex crystal films by an interface reaction. It was found that the three-dimensional MOF Zn(INA)2 obtained by dehydration of Zn(INA)2(H2O)4 could capture ammonia under dry conditions, without any influence on the structure, over several ...

This study examines the potential of CALF-20, a zinc-based metal–organic framework (MOF), synthesized through mechanochemistry, for carbon dioxide (CO2) capture using temperature swing adsorption (TSA) in post-combustion processes. Unlike conventional methods, mechanochemical synthesis reduces solvent us...

Bentonite also has the interesting property of adsorbing relatively large amounts of protein molecules from aqueous solutions. Therefore, it is uniquely useful in the process of wine making, where it is used to remove excessive amounts of protein from white wines. Were it not for this use of ...
stated that Mg-MOF-74 crystals comprising of Mg2+ sites with an open framework with a surface area of 1525 m2 g−1 prepared by sonication showed a greater CO2 capture of 350 mg g−1 at atmospheric ambiance.30 As MOF-74 holds open metal sites (Lewis acidic sites), CO2 is performed ...
