Metal-Ion-Dependent Gas Sorptivity of Elastic Layer-Structured MOFs



original image

Elastic layers: By comparing the gas adsorptivities of N2, O2, CO2, and H2 on two elastic layer-structured metal–organic frameworks (MOFs) with different metal ions, definite differences could be observed in O2, CO2, and H2 despite their structural similarity. In most cases of MOFs, the metal ion has been considered as a connector. However, the metal ion clearly has the potential to regulate gas adsorptivity especially in flexible MOFs.
