“…[61] Due to their thermal and chemical stability, Polyvinylidene fluoride (PVDF) polymers have been used as a constituent polymer material for MFC. Sharma et al [62] developed a CM by incorporating GO nanofiller into PVDF and cellulose acetate (CA) polymer blend. Cellulose acetate, PVDF and GO prevented biofouling, and enhanced proton conductivity and porosity with the ability to attract water; furthermore, the composite had chemical and thermal stability with improved surface area and membrane stability.…”

MFC can have dual functions; they can generate electricity from industrial and domestic effluents while purifying wastewater. Most MFC designs comprise a membrane which physically separates the cathode and anode compartments while keeping them electrically connected, playing a significant role in its efficiency. Popular commercial membranes such as Nafion, Hyflon and Zifron have excellent ionic conductivity, but have several drawbacks, mainly their prohibitive cost and non‐biodegradability, preventing the large‐scale application of MFC. Fabrication of composite materials that can function better at a much lower cost while also being environment‐friendly has been the endeavor of few researchers over the past years. The current review aims to apprise readers of the latest trends of the past decade in fabricating composite membranes (CM) for MFC. For emphasis on environmental‐friendly CM, the review begins with biopolymers, moving on to the carbon‐polymer, polymer‐polymer, and metal‐polymer CM. Lastly, critical analysis towards technology‐oriented propositions and realistic future directives in terms of strengths, weakness, opportunities, challenges (SWOC analysis) of the application of CM in MFC have been discussed for their possible large‐scale use. The focus of this review is the development of hybrid materials as membranes for fuel cells, while underscoring the need for environment‐friendly composites and processes.

“…Lower membrane rejection is achieved by increasing water permeability [17,39]. PVDF membrane anti-fouling properties improved with the addition of CA, which has an excellent anti-fouling performance and minimizes interaction between MB and surface membrane [40]. The washing treatment performed before the FRR test improved the anti-fouling value of the PVDF/CA membrane.…”

Cellulose derivatives from natural resources continuously develop to find the best hydrophobic polymer-based membrane technology performance. This study was conducted to improve the hydrophilicity, performance, and anti-fouling of polyvinylidene fluoride (PVDF) membrane with cellulose acetate (CA) filler synthesized from screw pine (Pandanus tectorius) leaf cellulose. CA was synthesized by the Fischer esterification mechanism and the PVDF membrane was fabricated using the phase inversion method with 0.3% CA concentration. FTIR analysis of CA shows an absorption at 1700 cm−1 suggesting that the hydroxyl group of cellulose had been successfully substituted with an ester group (C=O), and CA has a high degree of substitution (DS) value of 3.50. Adding CA improved the hydrophilicity and anti-fouling properties of up to 86.45% of PVDF membranes. Furthermore, CA increased the value of water permeability 2–3 times than pristine PVDF membrane. The presence of CA enhanced the porosity of the PVDF membrane, which promoted the membrane's effectiveness for MB filtering. As a result, CA from screw pine leaf cellulose has promising features as a filler for PVDF membranes and potential dye filtration.

“…In this direction, several methods for removing contaminants from aqueous solution have been documented, including coagulation, adsorption, ion exchange, membrane filtration, precipitation, and flocculation. − Among them, adsorption and membrane filtration methods are frequently utilized not only for Pb 2+ removal but also for overall water treatment . However, for large-scale applications, membrane filtration technology is considered a more pronounced method.…”

An important concern for the environment is the toxicity of lead ions in aqueous solutions. In the present research, a nitrogen-enriched nanoporous polytriazine (NENP) is synthesized (SABET ∼ 700 m2 g–1), which works well as an adsorbent to remove Pb2+ from water bodies. In batch adsorption mode, 5 mg of NENP having a high nitrogen content (∼52%) is capable of reducing the concentration of Pb2+ from 1.6 ppm to <10 ppb within 10 min, at 298 K and a pH of 7. The maximum adsorption capacity of 537 mg g–1 is estimated in 10 min for 600 ppm of Pb2+ solution having a pH of 7. Meanwhile, a mixed matrix membrane designated as N-MMM was fabricated using NENP as the active adsorbent and characterized by field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and N2 sorption analysis. In a cross-flow membrane setup, N-MMM with the flux of 16.2 L m–2 h–1 can treat 5 L of an aqueous solution containing 1.6 ppm of Pb2+ and provide safe drinking water (<10 ppb by WHO) for 300 min within the permissible limit (WHO) at 2 bar transmembrane pressure and a cross-flow velocity of 1L/M. N-MMM exhibits a remarkably high removal efficiency of 99.4% and good retention ability up to 3 consecutive cycles. These findings will be beneficial for the cost-effective production of metal-free heteroatom-enriched nanoporous materials for efficient removal of Pb2+ ions from water bodies.
