“…A comparison of UiO-66 and its derivatives shows that the overall structural crystallinity remained intact, despite the use of different ligands. The peaks observed here are consistent with the diffraction peaks previously reported for UiO-66 [ 49 , 50 , 51 , 52 , 53 ]. Next, the N 2 adsorption–desorption isotherm measured at 77 K ( Figure 3 b) clearly depicted that the UiO-66 nanocrystals possess high N 2 sorption at low P/P o .…”

Nanocrystalline UiO-66 and its derivatives (containing -NH2, -Br, -(OH)2) were developed via pre-synthetic functionalization and incorporated into a polyimide membrane to develop a mixed-matrix membrane (MMM) for CO2/N2 separation. Incorporation of the non-functionalized UiO-66 nanocrystals into the polyimide membrane successfully improved CO2 permeability, with a slight decrease in CO2/N2 selectivity, owing to its large accessible surface area. The addition of other functional groups further improved the CO2/N2 selectivity of the polymeric membrane, with UiO-66-NH2, UiO-66-Br, and UiO-66-(OH)2 demonstrating improvements of 12%, 4%, and 17%, respectively. Further evaluation by solubility–diffusivity analysis revealed that the functionalized UiO-66 in MMMs can effectively increase CO2 diffusivity while suppressing N2 sorption, thus, resulting in improved CO2/N2 selectivity. Such results imply that the structural tuning of UiO-66 by the incorporation of various functional groups is an effective strategy to improve the CO2 separation performance of MMMs.

Mixed Matrix Membranes (MMMs) of UiO-66-NH 2 nanoparticles dispersed in Cellulose Acetate (CA) were prepared with filler loading of 2-20 wt%. MMMs were tested for the upgradation of model biogas (60%-40%) mixture of CH 4 /CO 2 at a feed pressure of 2 bar and 1.5 bar. Detailed characterization of MMMs was performed with Fourier transform infrared spectroscopy (FTIR), Thermo-gravimetric analysis (TGA), Differential scanning calorimetry (DSC), and Field emission scanning electron microscopy (FESEM) to investigate the physical and thermal properties. MMMs formed are defects-free, voids-free, and without polymer rigidification, indicating a better filler polymer interface. MMMs showed improved CO 2 permeability while retaining the CO 2 /CH 4 selectivity. The 10 wt.% UiO-66-NH 2 /CA MMM showed optimum gas separation performance with CO 2 permeability of 11 Barrer and CO 2 /CH 4 selectivity of 10. The UiO-66-NH 2 /CA MMMs performed better when compared to the pure CA membrane. The experimental permeability and selectivity data were compared with the predicted data using Maxwell, Lewis-Nielsen, Higuchi, and Bruggeman's model.

The booming of global environmental awareness has driven the scientific community to search for alternative sustainable approaches. This is accentuated in the 13th sustainable development goal (SDG13), climate action, where urgent efforts are salient in combating the drastic effects of climate change. Membrane separation is one of the indispensable gas purification technologies that effectively reduces the carbon footprint and is energy‐efficient for large‐scale integration. Metal–organic frameworks (MOFs) are recognized as promising fillers embedded in mixed matrix membranes (MMMs) to enhance gas separation performance. Tremendous research studies on MOFs‐based MMMs have been conducted. Herein, this review offers a critical summary of the MOFs‐based MMMs developed in the past 3 years. The basic models to estimate gas transport, preparation methods, and challenges in developing MMMs are discussed. Subsequently, the application and separation performance of a variety of MOFs‐based MMMs including those of advanced MOFs materials are summarized. To accommodate industrial needs and resolve commercialization hurdles, the latest exploration of MOF materials for a harsh operating condition is emphasized. Along with the contemplation on the outlook, future perspective, and opportunities of MMMs, it is anticipated that this review will serve as a stepping stone for the coming MMMs research on sustainable and benign environmental application.
