“…Besides, this hybrid membrane offers not only separation but also adsorption coupled with photocatalytic properties simultaneously, making it the most suitable approach to be applied for treating industrial dye effluent. Chang et al, [50] fabricated a flexible-structured SiO2/MIL-100(Fe) fibrous membrane via immobilization of MIL-100(Fe) on the SiO2 fiber surface (Figure 7) for RhB dye degradation under visible light irradiation. This hybrid photocatalytic membrane possesses a 12.6 times larger specific surface area of 79.11 m 2 /g than that of other reported fibrous membranes, which enhanced dye degradation up to 95% within 70 min irradiation with a reaction rate constant of 0.05 min -1 .…”

“…7. Fabrication steps (a) and SEM image(b) of SiO2/MIL-100(Fe) fibrous membrane [50] MIL-100(Fe) has excellent capability in dyes removal; however, the hydrophobic nature of MIL-100(Fe) limits the development of MIL-100(Fe)-based membrane [51]. Recently, Cho et al, [52] modified MIL-100(Fe) by doping it with chitosan, then employed to PVDF matrix to enhance an antibacterial property, as shown in Figure 8.…”

Dye effluent released from the industries is one of the most severe environmental concerns due to their potential adverse effects on human health. There are many obstacles encountered in degrading dye materials as they are not only very stable to light and heat but also resistant to biodegradation and oxidation reactions. Currently, porous metal-organic frameworks (MOFs), an important class of advanced functional materials due to its novel coordination structures and diverse topologies, have shown potential applications in various fields, including dye removal. Among the highly water stable MOFs, Ferric-based MOFs like iron (III) trimesate, which is also known as MIL-100(Fe), is favorably ascribed by its simple synthesizing method as well as its wide availability. Herein, this paper summarized the recent progress achieved by MIL-100(Fe) in removing different types of dye, together with its sustainable preparation method.

“…[20][21][22][23] Therefore, immobilizing MOFs into suitable matrix was an interesting solution to overcome these catalysts disadvantages. [20] Thanks to polymers exceptional properties including chemical and thermal stability as well as their flexibility and good mechanical properties, associating them with MOFs inside or outside their pores, was also a considerable solution to enhance the workability and the processability of these materials. [21,24] Indeed, Zhang et al have modified the surface of different MOFs by their association with PDMS layer, deposited via a thermal process, ameliorating then the MOFs stability towards water degradation.…”

“…However, these catalysts are generally synthesized in powder dispersed form with poor chemical stability and processability which limit their catalytic applications where shaped catalysts are generally more desired. Indeed, thanks to their enhanced mechanical properties and their resistance to high applied wastewater flow, immobilized photocatalysts can be recycle and reuse through facile processes, avoiding then supplementary expensive and time‐consuming regeneration steps [20–23] . Therefore, immobilizing MOFs into suitable matrix was an interesting solution to overcome these catalysts disadvantages [20] .…”

Metals Organic Frameworks (MOFs) are promising crystalline, embrittled materials generally produced in powdering form with varied remarkably functionalities. In contrary, polymers are flexible and processable materials. Therefore, obtaining shaped solids gathering polymer malleability and MOFs properties such as their photocatalytic activities, have attracted many researchers' attention. This work, reports the successful fruitful incorporation of two different Fe-based MOFs into a polymer matrix via a facile and cheap photopolymerization process upon mild visible light irradiation at 405 nm. The as-prepared photocomposites display excellent stability and photocatalytic performance for several Acid Black degradation cycles. Hence, approximatively, 95 % of this model dye is decomposed by the two MIL-100(Fe)/polymer and MIL-88 A(Fe)/polymer composites under just 30 min of UV-Visible lamp irradiation. Incorporation of the MOFs into the polymer is confirmed by several techniques including Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray analysis (EDX), Transmission Electron Microscopy (TEM), X-Ray Diffraction analysis (DRX), Fourier-Transform Infrared Spectroscopy (FTIR). Furthermore, these photocatalysts exhibit a high thermal stability, excellent rigidity and low band gap energy characterized by Thermogravimetric Analysis (TGA), Atomic Force Microscopy (AFM), Dynamic Mechanical Analysis (DMA) and UV-Visible diffuse reflectance spectroscopy, respectively.

Metal-organic frameworks (MOFs), an emerging class of porous organic-inorganic hybrid materials, have shown great potential for water and wastewater treatment applications. However, pure MOF powders have limited practical applications in water treatment due to their insolubility, poor processability, brittleness, safety hazard from dust formation, and difficult separation from aqueous solutions. Thus, exploring potential MOFs composites with improved separation performance is of great importance. The marriage of MOFs with electrospun nanofiber with forethought into the final product's morphology, structure, and chemistry has opened up new opportunities for efficient wastewater treatment. The present review exhaustively summarizes the strategies to integrate MOFs into nanofibers via electrospinning to remove various pollutants (i.e., organic dyes, heavy metal ions, pharmaceuticals, personal care products, oily compounds, organic solvents, etc.) via adsorption, photodegradation, and membrane filtration. Besides, the most recent advances of electrospun MOF nanofibers for wastewater treatment and their current challenges and future outlook are delineated.
