“…The bands corresponding to C=C vibration, located at 1362 and 1451 cm −1 , are observed in both the precursor H 3 BTC and the synthesized Fe-BTC nanopowders. Moreover, the band at 1109 cm −1 is related to the metalorganic group C-O-Fe [31]. This information verifies the MOF nature of Fe-BTC material, in agreement with the XRD pattern previously reported.…”

A semi-crystalline iron-based metal-organic framework (MOF), in particular Fe-BTC, that contained 20 wt.% Fe, was sustainably synthesized at room temperature and extensively characterized. Fe-BTC nanopowders could be used as an efficient heterogeneous catalyst for the synthesis of dihydroxybenzenes (DHBZ), from phenol with hydrogen peroxide (H2O2), as oxidant under organic solvent-free conditions. The influence of the reaction temperature, H2O2 concentration and catalyst dose were studied in the hydroxylation performance of phenol and MOF stability. Fe-BTC was active and stable (with negligible Fe leaching) at room conditions. By using intermittent dosing of H2O2, the catalytic performance resulted in a high DHBZ selectivity (65%) and yield (35%), higher than those obtained for other Fe-based MOFs that typically require reaction temperatures above 70 °C. The long-term experiments in a fixed-bed flow reactor demonstrated good Fe-BTC durability at the above conditions.

“…Dorosti and Alizadehdakhel (2018) studied the effects of FeBTC loading on CO 2 /CH 4 separation performance of PEBAX 1657 membranes; they fabricated MMMs with FeBTC loading between 5 and 40% wt%. 90 They reported a gradual increase in CO 2 permeability with FeBTC loading, with a maximum CO 2 permeability of 425.4 barrer for 40 wt% FeBTC loading; however, the peak CO 2 /CH 4 selectivity was 22.2 for MMMs with 20 wt% FeBTC loading which started to decrease as the FeBTC loading increased. Shete et al 61 reported the effects of feed pressure on MMMs made with CuBDC (12 wt% loading) and Matrimid 5,218, they performed experiments at 2, 5, 10, 15 and 20 Bar for both pure Matrimid 5,218 and MMM.…”

“…It was noted that the CO 2 /CH 4 selectivity increased without any decrease in CO 2 permeability, instead the CO 2 permeability for 6FDA‐DAT‐Ni 2 (dobdc)‐15% MMM increased to 63.9 barrer from 55.8 barrer for 6FDA‐DAT membrane.

Mixed‐matrix membranes (MMMs) have been studied widely in the field of gas separation due to their potential to overcome performance barriers found in traditional polymeric membranes. Most polymeric membranes exhibit a trade‐off between permeation and selectivity, which has limited their development in many challenging separation applications. One solution to this issue utilizes the introduction of fillers into the polymer matrix to produce MMMs. Out of the many different fillers, metal–organic frameworks stand out as a promising candidate due to their highly tunable structure, molecular sieving effect, and superior compatibility with the polymer matrix. This review will provide an in‐depth look into the basic mechanisms of MMMs for gas separation and different approaches to model the permeation of gases through the membrane. In addition, challenges facing the field and recent research trends for MMMs will be discussed as well as their many applications for different gas separations. Finally, some insight on the future direction for MMMs will be covered, focusing on many intriguing opportunities and challenges that must be further explored to advance this technology.
