“…[12] In a representative work, Zn-MOF (interaction between carboxylate and zinc ions) and polyvinyl alcohol (PVA) were homogeneously dispersed in acetic acid solvent followed by appropriate electrospinning process, resulting in Zn-MOF/PVA nanofibrous composite. [41] It could be clearly seen from the SEM images that Zn-MOF particles retained the original crystalline structure, and the particle size was 38 nm (Figure 9b). Incorporation of Zn-MOF ameliorate the physicochemical performance of this nanofibrous composite.…”

“…Also, modifying organic ligands or grafting organic functional groups with diversified functions is another method to achieve the desired surface area and special structure. Although solvothermal/hydrothermal, [4,39] ultrasound-assisted, [40] electrospinning, [41] microwave-assisted, [42] spray-drying synthesis [43] methods, etc. have been widely reported for synthesizing MOFs, the hydrothermal/solvothermal techniques are still the mainstay in sewage treatment applications.…”

“…In addition, electrospinning technology with simple operation and low cost has been widely used to fabricate MOFs. [24,41] In this preparation process, raw materials are directly mixed into precursors, and the subsequent electrospinning yields MOF nanofibers with distinctive structure and application properties.…”

ions, synthetic dyes, antibiotics, and other substances in groundwater and wastewater discharged from factories have caused serious harm to the environment and human health. Therefore, it is vital to develop efficient water pollution treatment methods.The heavy metal ions discharged from factories into rivers and lakes can cause diffusion and pollution. Highly toxic heavy metal ions are easy to accumulate in organisms because they are not biodegradable. [1] Organic dyes and radioactive pollutants produced in industrial production will diffuse into soil and water resources, endangering the safety of animals, plants and human life. [2] The leakage of antibiotics in the fields of biology and medicine will destroy the balance and stability of the ecosystem. [3] An enormous number of pollutants are persistent and difficult to degrade. Scientists have been committed to developing various technologies and materials for removing pollutants from water environment. Nevertheless, effectively purifying sewage still remains a tough challenge.Various techniques are used for sewage purification to remove pollutants in the environment. Common methods include separation, [4] absorption, [5] photocatalytic degradation, [6] and membrane filtration. [7] However, traditional absorbents and catalysts such as zeolites, activated carbons, organic resins, etc. have poor pollutant removal capabilities. [8] Traditional adsorbents, such as carbons and clay minerals, exhibit weak ionic affinity and low adsorption efficiency for metals. [9] Furthermore, partial catalysts possess inferior charge separation efficiency, recyclability, and chemical stability, which is likely to cause secondary pollution to water sources, and does not meet the requirements of green, energy saving, and renewable in the field of modern environment protection. [10] Therefore, researchers have been trying to exploit an efficient and economical composite material with superb specific surface area, high separation and strong reusability. [11] Metal-organic framework (MOF) is a new type of composite material self-assembled by metal ions or metal clusters and organic linkers. [12] As a novel type porous material, MOF has adjustable pore size, superior specific surface area and excellent porosity, and its performance is more superiority than traditional materials such as zeolite and clay. [13] They have raisedThe ever-expanding scale of industry and agriculture has led to the gradual increase of pollutants (e.g., heavy metal ions, synthetic dyes, and antibiotics) in water resources, and the ecology and wastewater are grave problems that need to be solved urgently and has attracted widespread attention from the research community and industry in recent years. Metal-organic frameworks (MOFs) are a type of organic-inorganic hybrid material with a distinctive 3D network crystal structure. Lately, MOFs have made striking progress in the fields of adsorption, catalytic degradation, and biomedicine on account of their large specific surface and well-developed pore structure. This...

“…Of these techniques, electrospinning is the most promise due to its simplicity, scalability, and versatility in producing high‐performance nanofibers (Li and Xia, 2004; Xue et al, 2017; Selatile et al, 2018; Xue et al, 2019). Some recent studies have used nanospun composites to treat both polluted wastewater (Sargazi et al, 2019b; Shahryari et al, 2020) and gas effluents (Sargazi et al, 2019a).…”

This study presents a bench‐scale study on the dynamic removal of arsenic from wastewater by an adsorption membrane consisting of a polycaprolactone matrix with iron‐intercalated montmorillonite filler. A 2K factorial design of experiment was employed to study the effect of different adsorption parameters; namely, flow rate, initial influent concentration, and thickness of adsorbent sheets on breakthrough time. Longer breakthrough times were associated with low flow rates, low initial influent concentrations, and thick nanofiber membrane. The bed depth service time (BDST) approach was used to model adsorption kinetics. An empirical equation for predicting service time of the adsorbent membrane was obtained and was used to design the bench‐scale column. The performance of the adsorption column was accurately predicted by the BDST model. This practical, nanocomposite‐based adsorption column offers a promising alternative wastewater treatment for addressing arsenic contamination in water.

In this study, Ni-MOF was synthesized via ultrasound irradiation under optimal conditions, which included an ultrasound power of 370 W, time duration of 20 minutes, and a temperature of 25 oC. The final Ni-MOF nanostructures were immobilized in PVA fibrous polymeric network using under optimal conditions (concentration: 8 wt %; the nozzle tip with flow rates of 0.10 mL/h; temperature: 25 oC and humidity: 22 %; voltages: 20 kV; spinning distance: 12 cm) of electrospinning. To characterize the final composition, various analyses were used. The presence of functional groups in structures was confirmed by FTIR. The Ni-MOF sample was uniformly synthesized on the surface of PVA, as evidenced by SEM and Mapping elemental analysis. The BJH technique validated the effect of the substrate's role in increasing the surface area of the final products. The final products of the Ni-MOF/PVA fibrous network were used as a novel adsorbent in the adsorption of CH4 gas.
