Bimetallic Metal organic framework (MOF) has garnered interest over the years with its application in various environmental remediation. In this study, Fe-Al-1,4-Benzene di-Carboxylic acid (FeAl(BDC)) MOF was synthesized, and adsorptive removal of Rhodamine B dye in batch and unique hybrid FeAl (BDC)-River sand fixed-bed column was achieved. The experimental data from the batch studies corroborated well with the Pseudo second-order (PSO) and Freundlich adsorption isotherm models. Furthermore, a fixed-bed column study was conducted to assess the effect of varying flow rate (2, 5, 8 mL/min), bed height (5, 9, 13 cm), and feed concentration (10, 20, 30 mg/L) on the adsorption performance of FeAl(BDC) in continuous mode of operation. A uniform mixture of river sand and FeAl(BDC) by weight ratio (9:1) was achieved prior to packing the column. The column study reveals that Sand-FeAl(BDC) can achieve the maximum adsorption capacity of 113.05 mg/g at a flow rate of 5 mL/min, feed concentration of 20 mg/L, and bed height of 13 cm. The experimental data of the column study were successfully fitted with BDST, Thomas, Yoon-Nelson, and Dose-response models. The fitting parameter values from the BDST model raise the scope of possible upscaling of the fixed-bed column. Hence, it is proposed that these River sand-FeAl(BDC)-based filters can be widely used in areas facing critical contamination and in poor communities with a high demand for water.

In the last two decades, metal−organic frameworks (MOFs) have attracted overwhelming attention. With readily tunable structures and functionalities, MOFs offer an unprecedentedly vast degree of design flexibility from enormous number of inorganic and organic building blocks or via postsynthetic modification to produce functional nanoporous materials. A large extent of experimental and computational studies of MOFs have been focused on gas phase applications, particularly the storage of low‐carbon footprint energy carriers and the separation of CO2‐containing gas mixtures. With progressive success in the synthesis of water‐ and solvent‐resistant MOFs over the past several years, the increasingly active exploration of MOFs has been witnessed for widespread liquid phase applications such as liquid fuel purification, aromatics separation, water treatment, solvent recovery, chemical sensing, chiral separation, drug delivery, biomolecule encapsulation and separation. At this juncture, the recent experimental and computational studies are summarized herein for these multifaceted liquid phase applications to demonstrate the rapid advance in this burgeoning field. The challenges and opportunities moving from laboratory scale towards practical applications are discussed.

“…Among different types of MOFs, MIL-53 series has shown to be effective for the removal of organic dyes from organic solvents. [39] Given the intricate channels and hierarchical pore sizes are retained as the solid structure of MOF crystals are constructed, we expect that on MIL-53(Al)-NH 2 FMMMs will perform well for removing organic dye contaminants from organic solvents. In addition, as control group, we also report the performance of MIL-96(Al) FMMM for organic dye removal.…”

range of appealing properties are observed on MOFs, such as high surface areas and porosity, ordered open channels, and tunable functionalities, making them attractive for applications in gas storage, [2,3] separation, [4,5] catalysis, [6,7] sensing, [8] and environmental decontamination. [9] However, their utilization in above applications is limited due to the brittle nature in powder phase. As a result, further handling and processing is required for industrial applications. As reported in literature, MOF-membrane integration is a robust strategy to extend the exceptional properties of MOFs by providing them the required structural integrity, this can be achieved by growing MOF layers on substrates [10][11][12] or by incorporating MOF crystals into mixed matrix membranes (MMMs). [13][14][15] The later approach is the most attractive scenario, because high MOF loadings can be achieved. The MMMs show marked advantages to the single component, since MOF crystals provide rich molecular sieving sites and the polymeric membrane substrates are easy to handle and process.While the MOF-based MMMs exhibit excellent priorities, there still remain limitations on the mixed-matrix approach: [14,16] i) trade-offs between MOF loadings and membrane functions. Specifically, high MOF loadings generally increase the possibility of phase separation, decreasing strength, and creating cracks, while low loadings usually result in insufficient selectivity due to the reduced number of active sites; and ii) the existence of by-pass caused by interfacial voids between polymers and MOFs would inevitably hinder the real separation performance, which leads to an unpredictable and low selectivity.In order to eliminate these concerns, we propose a robust methodology to produce substrate-free MOF membranes via a pseudomorphic replication synthesis route. Pseudomorphic replication, stemmed from the natural pseudomorphic mineral replacement phenomenon, had been initially introduced by Kitagawa and his coworkers concerning shaped and assembled synthesis of MOF structures. [17] Through the coordination-driven pseudomorphic replication of MOF conversion, precise spatial localization of MOF crystal crystallization can be achieved. [18] Additionally, it was observed that the MOF replica would retain the original physical structure, including shapes and dimensions from its parent phase. Inspired by Metal organic framework (MOF)-based adsorptive membranes are attractive materials in high flux separation and/or in abatement of hazardous materials. However, fabrication of continuous MOF membrane with ultra-high loading and anti-solvent property is a challenging task. Here, the authors report a coordination replication synthetic approach via a morphological replacement procedure that employs pre-shaped Al 2 O 3 microfiltration membrane to produce freestanding MOF multifunctional membrane (FMMMs). The authors achieve precise control of crystal size, morphology, and orientation on the FMMMs. Moreover, the intrinsic porous structure inherited from Al 2 O 3 p...
