Densification and shaping of pure Cu-BTC powders using a solid-state chemical transformation

Wendy Lee Queen, Mathieu Soutrenon, Jordi Espin Marti, Mehrdad Asgari, Vikram Vinayak Karve, Alexandre Mabillard

MOFs are a class of porous crystalline materials whose unique properties have led to applicability in several fields ranging from gas adsorption to drug delivery. Despite their high potential, MOFs are usually found as fine powders, a property that can lim ...

Dynamic CO2 sorption on MgO-based sorbent in the presence of CO and H2O at elevated pressures

Seongmin Jin, Gina Bang

The presence of gas species other than the target adsorbate in practical conditions causes complications in implementing a sorption-based process because of synergistic or detrimental effects on the sorption mechanism. MgO-based sorbents have attracted mas ...

Characterization of metal organic frameworks of interest for gas adsorption/separation applications

Mehrdad Asgari

Metal-Organic Frameworks (MOFs) are a class of porous materials that are applicable in many energy and environmentally relevant areas, due to their unique features including unprecedented internal surface areas and easy chemical tunability. Gas separation ...

Enhancing MOF performance through the introduction of polymer guests

Wendy Lee Queen, Jordi Espin Marti, Daniel Teav Sun, Shuliang Yang, Li Peng, Mehrdad Asgari, Olga Trukhina, Ilia Kochetygov, Vikram Vinayak Karve, Anita Justin

In this contribution, recent advances in the construction of MOF-polymer composites and their corresponding applications are briefly reviewed. The appearance of such architectures is becoming prominent in recent literature, due to the fact that the union o ...

An In-Situ Neutron Diffraction and DFT Study of Hydrogen Adsorption in a Sodalite-Type Metal-Organic Framework, Cu-BTTri

Michele Ceriotti, Wendy Lee Queen, Shuliang Yang, Mehrdad Asgari, Olga Trukhina, Safak Bulut, Ilia Kochetygov, Rocio Semino Barbaresi

Herein we present a detailed study of the hydrogen adsorption properties of Cu‐BTTri, a robust crystalline metal–organic framework containing open metal‐coordination sites. Diffraction techniques, carried out on the activated framework, reveal a structure ...
