“…In addition, MOFs possess one or several innate characteristics, including large surface area, large porosity, controllable pore size, designable structure, and good compatibility with polymers. − In view of this, MOF materials have been suggested as alternative nanofillers for improving membrane separation performance. A series of MOFs, including UiO-66-PSBMA, CuBTC, ZIF-8, ZIF-67, MIL-100(Fe), MIL-101(Cr), UiO-66-NH2, Cu-iMOFs, and NH2-MIL-101, were tested in ultrafiltration membranes for antifouling and exhibited enhancement of gas, pharmaceutical waste, natural organic matter, and oily wastewater separation. − Furthermore, MIL-101(Cr)-, ZIF-8 (mZIF)-, HKUST-1-, CuBTC-, and ZIF-93-based nanofiltration membranes were applied for the removal of endocrine-disrupting compounds, organic solvents, and divalent salts. − In continuation of research on recent progress, researchers have reported innovative casting solution strategies for the fabrication of TFN membranes with incorporation of different MOFs into selective PA layers; positive results have been achieved. The fabricated TFN membranes developed additional surface properties and demonstrated a significant increase in rejection and water permeability. ,− However, it has been noted that some MOF nanoparticles demonstrated poor stability in water and difficulty of dispersing in the aqueous phase.…”

Metal–organic framework (MOF) materials have received extensive attention for the design of advanced thin-film nanocomposite (TFN) membranes with excellent permselectivity. However, the relationship between the unique physicochemical properties and performance of engineered MOF-based membranes has yet to be extensively investigated. In this work, we investigate the incorporation of porous zinc-based MOFs (Zn-MOFs) into a polyamide active layer for the fabrication of TFN membranes on porous poly(phenylsulfone) (PPSU) support layers through an interfacial polymerization approach. The actual effects of varying the amount of Zn-MOF added as a nanofiller on the physicochemical properties and desalination performance of TFN membranes are studied. The presence and layout of Zn-MOFs on the top layer of the membranes were confirmed by X-ray photoelectron spectroscopy, scanning electron microscopy, and ζ potential analysis. The characterization results revealed that Zn-MOFs strongly bind with polyamide and significantly change the membrane chemistry and morphology. The results indicate that all four studied TFN membranes with incorporated Zn-MOFs enhanced the water permeability while retaining high salt rejection compared to a thin-film composite membrane. Moreover, the highest-performing membrane (50 mg/L Zn-MOF added nanofiller) not only exhibited a water permeability of 2.46 ± 0.12 LMH/bar but also maintained selectivity to reject NaCl (>90%) and Na2SO4 (>95%), similar to benchmark values. Furthermore, the membranes showed outstanding water stability throughout 72 h filtration and chlorine resistance after a 264 h chlorine-soaking test because of the better compatibility between the polyamide and Zn-MOF nanofiller. Therefore, the developed TFN membrane has potential to solve trade-off difficulties between permeability and selectivity. Our findings indicate that porous Zn-MOFs play a significant role in the development of a TFN membrane with high desalination performance and chlorine resistance.

“…Ultimately, the PhACs had been successfully adsorbed onto the MOF surface because of their robust porous features. Moreover, in comparison of MOF-based UF and activated carbon-based UF (AC-UF) hybrid schemes, the typical retaining rates of PhACs for the PAC-UF came out to be lesser than MOF-UF [34].…”

In recent years, the pharmaceutical field has significantly achieved magnificent progress owing to the necessities of human health and life; however, it also led to drastic environmental issues. The existence of pharmaceuticals in water bodies, which could cause adverse effects on human beings and environment, rose up distress worldwide. The pharmaceutical components found in water bodies have mainly two origins: manufacturing procedures in pharmaceutical industry and common usage of pharmaceutics. The essence of pharmaceutical wastewater (PWW) is intricate, including large amount of organic matter, high salt, microbial toxicity, and non-biodegradable. In sight of water scarcity means, it is essential to figure out and expand techniques for pharmaceutics derived wastewater in water management. Nevertheless, numerous treatment methods have been established to serve pharmaceutical wastewater including biological treatments, membrane technologies, hybrid technologies, advanced oxidation processes, absorption methods, etc. Recently, metal organic frameworks (MOFs), metallic ions clusters linked with organic bridging linkers, have been utilized in number of uses such as storage, separation, sensing, catalysis, adsorption, and many others. The viability of MOFs toward wastewater treatment (WWT) for various pollutants is fundamentally because of the extreme porosity, discrete pore structure, and superficial modification. This chapter highlights the origin and treatment of pharmaceutical wastewaters via the utilization of MOFs and their hybrid systems. A brief perception of the future work in the field has also been discussed.

“…Despite the unique properties of TiO 2 as a photocatalyst, its benefits are hindered due to its wide bandgap, which is UV‐activated, and the rapid recombination rate of charge carriers. A combination of TiO 2 with other semiconductor materials coupled with Graphitic carbon nitride (g‐C3 N4) can be an effective way for enhancing the photocatalytic activity under visible light [72–74] .

There is an increasing level of various pollutants and their persistence in aquatic environments. The improper use of antibiotics and their inefficient metabolism in organisms result in their release into aquatic environments. Antibiotic abuse has led to hazardous effects on human health. Thereby, efficient removal of pharmaceuticals, particularly antibiotics, from wastewater and contaminated water bodies is greatly interested in international research communities. Metal‐organic framework (MOF) materials, as a hybrid group of material containing metallic center and organic linkers, offer a porous structure that is highly efficient for removing different pollutants from contaminated water and wastewater streams. This article aims to review the recent advancement in using MOF‐based adsorbents and catalysts for the removal of pharmaceuticals, especially antibiotics, from polluted water. Applying MOFs‐based structures for removing antibiotics using photocatalytic removal and adsorptive removal techniques will be discussed and evaluated in this review paper. Various MOF‐based materials such as functionalized MOFs, MOF‐based composites, magnetic MOF‐based composites, MOFs templated‐metal oxide catalysts for removing pharmaceuticals, personal care products, and antibiotics from contaminated aqueous media are discussed. Furthermore, effective operational parameters on the adsorption, adsorption mechanisms, adsorption isotherms, and thermodynamic parameters are explained and discussed. Finally, in the concluding remarks, the challenges and future outlooks of using MOFs‐based adsorbents and catalysts for removing antibiotics are summarized.
