Title

Diffusion of gases and mixtures in the new MIL-140 materials

Abstract

A series of very stable Metal Organic Frameworks (MOFs), denoted as MIL-140, has been recently prepared. The 1D pore size of MIL-140-A is of 3.2 Å and could thus be used to separate CO2 from other gases in natural gas purification or CO2 capture from flue gas. Functionalised MIL-140-A, obtained after grafting Br and CH3 on the organic linker, have even smaller pore sizes and have therfore the potential to separate H2 and CO2. These separations require full understanding of the diffusion of the different gases and mixtures in the microporous frameworks. This can be obtained by a combination of QENS and molecular simulations.
