“…[10] Although there have been significant achievements in gas separation using MOF materials,i tr emains challenging to fabricate high selective gas membranes owing to the larger pore size of the most MOF materials than the typical size of gas molecules. [11] Furthermore,p hysical and chemical modifications of MOF particles and microporous supports is vital to improve the adhesion of the MOF selective layer and prevent the formation of nonselective voids. [12] Tu ning of MOFs in terms of pore size and shape is apractical approach to increase the selectivity of membranes through the sieving effect.…”

The effect of organic ligands on the separation performance of Zr based metal–organic framework (Zr‐MOF) membranes was investigated. A series of Zr‐MOF membranes with different ligand chemistry and functionality were synthesized by an in situ solvothermal method and a coordination modulation technique. The thin supported MOF layers (ca. 1 μm) showed the crystallographic orientation and pore structure of original MOF structures. The MOF membranes show excellent selectivity towards hydrogen owing to the molecular sieving effect when the bulkier linkers were used. The molecular simulation confirmed that the constricted pore apertures of the Zr‐MOFs which were formed by the additional benzene rings lead to the decrease in the diffusivity of larger penetrants while hydrogen was not remarkably affected. The gas mixture separation factors of the MOF membranes reached to H2/CO2=26, H2/N2=13, H2/CH4=11.

“…In one of the pioneer works, MOF-5 was investigated for the photocatalytic degradation of phenol in aqueous solutions [37]. Zn 3 (BTC) 2 films was also studied to degrade methylene blue (MB) [38]. However, due to the wide band gap of these MOFs, the degradation process could only proceed under UV-light irradiation.…”
