Impact of the functionalization onto structure transformation and gas adsorption of MIL-68(In).

ABSTRACT: A series of functionalization -NH₂, -Br and -NO₂ has been performed on MIL-68(In) material in order to improve the porosity features of the pristine material. The functional groups grafted onto the ligand and the molar ratios of the ingredient indicate a profound influence on product formation. With the incremental amount of metal source, product structures undergo the transformation from MIL-68 to MIL-53 or QMOF-2. The situation is different depending on the variation of the ligands. Gas (N₂, Ar, H₂ and CO₂) adsorption-desorption isotherms were systematically investigated to explore the impact of the functionalization on the porous prototypical framework. Comparison of adsorption behaviour of N₂ and Ar indicates that the po
