Surfactant-assisted synthesis of hierarchical NH2-MIL-125 for the removal of organic dyes

Hierarchical NH₂-MIL-125 were synthesized and an excellent dye removal performance was obtained.

A computational approach towards understanding hydrogen gas adsorption in Co–MIL-88A

The hydrogen adsorption is most favorable at the hollow site of Co–MIL-88A.

Screening of hypothetical metal-organic frameworks for H2 storage

Computational screening throughout a database containing ∼138 000 metal-organic frameworks (MOFs) has been performed to select candidate structures for hydrogen storage. A total of 231 structures (of which 79 contain paddle-wheel units) have been selected that meet the gravimetric and volumetric targets at 100 atm and 77 K. Grand Canonical Monte Carlo simulations have been performed to calculate the isotherms and select structures which meet the targets at 50 atm, and also to check the adsorption in the low pressure regime (1 atm). From this a reduced set of 18 structures has been analysed in more detail, regarding not only gravimetric and volumetric uptake but also pore size distribution and pore volume. A few structures with 3% gravimetric uptake at 1 atm and 77 K perform at the best level found so far.

Force field for ZIF-8 flexible frameworks: atomistic simulation of adsorption, diffusion of pure gases as CH4, H2, CO2 and N2

A full set of flexible force field parameters for ZIF-8, applied for its gas adsorption and diffusion, has been presented.

The required level of isosteric heat for the adsorptive/storage delivery of H2 in the UiO series of MOFs

The required level of isosteric heat of adsorption for efficient storage and delivery of H₂ in the UiO series of MOFs was theoretically predicted using molecular simulations.
