“…The functional groups present on the membrane surfaces were confirmed by ATR‐FTIR spectroscopy as shown in Figure 1(a). The bands around 1150 and 1238 cm −1 are attributed to symmetric and asymmetric vibrations of sulfone (SO) functional groups on the PES polymer 41,48 . The vibrational bands at 1007 and 1299 cm −1 are due to stretching vibrations of the COC group.…”

“…There are currently no published reports on the breakdown of IMD pesticide with the addition of Fe‐CeO 2 onto PES. Consequently, it is believed that adding Fe‐CeO 2 to PES will enhance its photocatalytic capabilities, flux, and antifouling qualities 41 . Additionally, it is thought that this approach will lessen the photocatalyst leaching into solution that occurs when powder catalysts are used and will thus minimize introducing secondary pollution after use.…”

The widespread accumulation of insecticides in water systems is a growing concern. This study reports efficient photodegradation of imidacloprid (IMD) insecticide using polyethersulfone (PES) membranes modified with iron‐doped cerium oxide (Fe‐CeO2). The work focuses on the modification of ultrafiltration polyethersulfone membranes with incremental amounts of Fe‐CeO2 photocatalysts (0.5–2.0 wt.%) using phase inversion method. An increase in Fe‐CeO2 content showed an improvement in surface roughness and porosity of membranes. Pure water flux (PWF) increased from 55.9 L m2 h−1 in M0 (PES) to 77.2 (M1, 0.5% Fe‐CeO2‐PES), 118.0 (M2, 1% Fe‐CeO2‐PES), 128.0 in M3 (1.5 wt.% Fe‐CeO2‐PES) and then decreased to 98.5 L m2 h−1 in M4 (2 wt.% Fe‐CeO2‐PES). This decrease is brought about by the high Fe‐CeO2 content, which minimizes the membranes' surface pores. Fe‐CeO2 photocatalysts are thought to give the membrane both hydrophilic and photocatalytic qualities because of their capacity to absorb light and create radical species that cause the photodegradation of IMD molecules. Consequently, under visible light irradiation, modified membranes demonstrated photocatalytic ability over IMD. Photocatalytic efficiencies of the membranes were found to be 5.2% (M0), 68.9 (M1), 75.8 (M2), 81.8 (M3), and 56.0% (M4), respectively, with M3 membranes showing the highest photocatalytic degradation efficiency and low leaching of metals. The remarkable performance observed by M3 membranes during both water filtration and photocatalytic performance may be an illustration of well dispersed photocatalyst which receives high absorption of light irradiation. Membranes with photocatalytic functionalities are tailored to exploit dual benefits of the membrane filtration and photocatalysis without compromising their original functions. However, maintaining the delicate balance of this phenomenon is still very challenging.

“…Recently, innovation in membrane processes for reliable water supply has earned wide attention. The membrane separation technologies (reverse osmosis [RO], nanofiltration, ultrafiltration [UF], and microfiltration) have been recognized as promising strategies primarily for food, petrochemical, and pharmaceutical processing, wastewater treatment, and desalination (Abdullah et al, 2023; Zrellia et al, 2023). Among the different separation techniques, ultrafiltration membranes have become widely accepted in the field of water treatment technologies because of their benefits, including simple operation, cost‐effectiveness, high efficiency, and lack of harmful byproducts.…”

Polymeric membranes have garnered great interest in wastewater treatment; however, fouling is known as their main limitation. Therefore, the blending of hydrophilic nanoparticles in polymeric membranes' structure is a promising approach for fouling reduction. Herein, a hydrophilic boehmite–tannic acid–graphene quantum dot (BM‐TA‐GQD) nanoparticle was synthesized and blended in a polyethersulfone polymeric membrane in different percentages. The fabricated membranes were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) images, water contact angle, porosity measurement, and antibacterial and antifouling properties. Surface SEM images of the modified membranes showed good dispersion of nanoparticles up to 0.5 wt%, which resulted in hydrophilicity and pure water flux enhancement. Based on AFM images, the mean roughness (Sa) of the fabricated membranes decreased from 2.07 to 0.84 nm for the bare and optimum membranes, respectively. In terms of performance, increasing the nanoparticle percentages up to 0.5 wt% resulted in the flux recovery ratio developing from 44.58% for the bare membrane to 71.35% for the 0.5 wt% BM‐TA‐GQD/PES membrane (optimum membrane). The antibacterial property of fabricated membranes was studied against biologically treated soft drink industrial wastewater (BTSDIW) as a bacterial source. The results showed that the turbidity of solutions containing permeated wastewater from the modified membranes (0.1, 0.5, and 1 wt% of BM‐TA‐GQD) was lower than that obtained from the unmodified membrane. These results confirmed the antibacterial properties of fabricated membranes. Finally, the optimal membrane (0.5 wt% BM‐TA‐GQD) was examined for post‐treatment of the BTSDIW. An effluent COD of 13 mg/L and turbidity of 2 NTU showed a successful performance of the filtration process.Practitioner Points Ultrafiltration PES membranes were modified by different loadings of BM‐TA‐GQD. Hydrophilicity improvement was achieved by adding BM‐TA‐GQD nanoparticles. Expansion of size and number of macro‐voids in modified membranes was confirmed. Membrane roughness was reduced in the BM‐TA‐GQD blended membranes. The optimum membrane was efficient in COD and turbidity removal.

“…It may be possible to fabricate new electrodes with enhanced quality, lower cost, and higher CO acceptance for PEMFCs and direct methanol membrane fuel cells by extending such nanowire-based 3D electrodes to other material classes. Abdullah et al found the inclusion of hydrophilic WO 2.89 nanomaterial [ 52 ] limited membrane fouling throughout the photocatalytic process, and reactive radicals could react with adsorbate species and reject them, increasing the membrane’s hydrophilic nature [ 53 ]. Sathya et al [ 54 ] also found that adding WO 3 greatly improved the biofouling properties of a PEI membrane by using BSA and humic acid as a model sample of pollutants in wastewater.…”

In this study tungsten oxide and graphene oxide (GO-WO2.89) were successfully combined using the ultra-sonication method and embedded with polyphenylsulfone (PPSU) to prepare novel low-fouling membranes for ultrafiltration applications. The properties of the modified membranes and performance were investigated using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), contact angle (CA), water permeation flux, and bovine serum albumin (BSA) rejection. It was found that the modified PPSU membrane fabricated from 0.1 wt.% of GO-WO2.89 possessed the best characteristics, with a 40.82° contact angle and 92.94% porosity. The permeation flux of the best membrane was the highest. The pure water permeation flux of the best membrane showcased 636.01 L·m−2·h−1 with 82.86% BSA rejection. Moreover, the membranes (MR-2 and MR-P2) manifested a higher flux recovery ratio (FRR %) of 92.66 and 87.06%, respectively, and were less prone to BSA solution fouling. The antibacterial performance of the GO-WO2.89 composite was very positive with three different concentrations, observed via the bacteria count method. These results significantly overtake those observed by neat PPSU membranes and offer a promising potential of GO-WO2.89 on activity membrane performance.
