Cooperative Adsorption by Porous Frameworks: Diffraction Experiment and Phenomenological Theory

Cooperative Adsorption by Porous Frameworks: Diffraction Experiment and Phenomenological Theory
Farid Nouar, Yaroslav Filinchuk, Dmitry Chernyshov, Christian Serre, Iurii Dovgaliuk
Two nanoporous frameworks, γ-Mg(BH4)2 and MIL-91(Ti), with different levels of structural flexibility upon guest adsorption-desorption, were examined with in situ X-ray diffraction. Both frameworks exhibit a cooperative guest adsorption correlated with a lattice deformation. The observed experimental scenarios are rationalized with a mean field Gorsky–Bragg–Williams (GBW) approach for the lattice-gas Ising model, which enables the characterization of the thermodynamics of adsorption not only for the total uptake, but also for every specific guest site. More information can be found in the Full Paper by I.  Dovgaliuk, D. Chernyshov et al. (DOI: 10.1002/chem.201702707).
