“…The inhibition percentage of ZFO-CTAB MNPs was found to be 94.24, 95.29, and 95.63% for Escherichia coli , Salmonella typhi , and Pseudomonas aeruginosa , respectively. The high inhibition percentage (> 94%) of ZFO-CTAB MNPs is due to their small particle size (34.03 nm) and high surface area (32.95 m 2 /g), which allow them to penetrate inside the bacterial cell wall and damage the cell via a chemical degradation mechanism by reactive oxygen species generation such as hydrogen peroxide (H 2 O 2 ) and super-oxide (O 2− ) (Asogekar et al , 2021; Janani et al , 2021; Zhang et al , 2019). The pathogens tested are MDR bacteria, which cause a variety of life-threatening infections.…”

“…Because of their tailorable physical and chemical properties, nanoparticles (NPs) including spinel oxides hold the promise of not only combating antibiotic-resistant bacteria but also serving as antibiotic carriers (Amiri et al , 2019; Baptista et al , 2018; Qi et al , 2020). Owing to their less toxicity and biocompatibility (Amiri et al , 2019), various magnetic NPs (MNPs)-based on spinel ferrites, such as CoFe 2 O 4 (Gheidari et al , 2020), ZnFe 2 O 4 (Mandal et al , 2016), CdO/ZnFe 2 O 4 (Janani et al , 2021), Cu 0.95 Ag 0.05 Fe 2 O 4 (Gomes et al , 2018) and Co 0.5 Zn 0.5 Fe 2 O 4 (Asogekar et al , 2021) have been tested for antibacterial activity.…”

Purpose The purpose of this research is to assess the removal of oil spills from the seawater surface as well as the antibacterial activity of ZnFe2O4-cetyltrimethylammonium bromide (CTAB, cationic surfactant) magnetic nanoparticles (ZFO-CTAB MNPs). Design/methodology/approach A CTAB-assisted sol–gel method was used to synthesize ZFO-CTAB MNPs. X-ray powder diffraction and Fourier transform infrared spectroscopy were used for ZFO-CTAB MNPs characterization. Also, the magnetic force and apparent density of ZFO-CTAB MNPs were determined. The oil spill cleanup was investigated by using the gravimetric oil removal (GOR) technique, which used ZFO-CTAB MNPs as oil absorbent material and four oil samples (crude, diesel, gasoline and used oil) as oil spill models. The antibacterial activity of ZFO-CTAB MNPs against Gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli and Salmonella typhi) was investigated by using the optical density method. Findings The results revealed that, when the amount of ZFO-CTAB was 0.01 g, gasoline oil had the highest GOR (51.80 ± 0.88 g/g) and crude oil had the lowest (11.29 ± 0.82 g/g). Furthermore, for Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa, ZFO-CTAB MNPs inhibited bacterial growth with a higher percentage (94.24%–95.63%). Originality/value The applications of ZFO-CTAB MNPs in the cleanup of oil spills from aqueous solutions, as well as their antibacterial activity. The results showed that ZFO-CTAB MNPs are a promising material for removing oil spills from bodies of water as well as an antibacterial agent against Gram-negative bacterial strains.

“…The basic structure of A 2 B 3 (Fe 2 O 3 ) was derived from Fe 2+ O. (Fe 3+ ) 2 O 3 , where divalent ions such as Mn, Zn, Cu, etc, are replaced by Fe 2+ place, which can be applied in several fields [5][6][7][8][9]. Rezlescu et al discussed that trivalent rare earth impurities have large ionic radii and so can improve their structural, optical, magnetic, and electrical properties [10].…”

One of the global challenges for living things is to provide pollution and harmful microbes-free environment. In this study, magnetically retrievable spinel-structured manganese zinc ferrite (Mn0.5Zn0.5Fe2O4) (MZF) was synthesized by a facile solvothermal method. Further, the MZF with different weight percentages (10wt%, 50wt%, and 80wt%) were supported on reduced graphene oxide (rGO). The phase purity and morphology of MZF and MZF/rGO nanocomposite were confirmed by X-ray diffraction technique and scanning electron microscopy, respectively. The Fourier transform infrared spectroscopy, Raman, UV-visible spectroscopy, and thermogravimetric analyses of the as-synthesized nanocomposites were examined for the detection of various chemical groups, band gap, and thermal properties, respectively. The MZF/rGO nanocomposite exhibited significant antibacterial and antifungal activity against Eggerthella lenta, Enterococcus faecalis, Klebsiella pneumonia, Pseudomonas aeruginosa, and Candida albicans compared to bare MZF and rGO. The high surface area of rGO plays a crucible role in antimicrobial analysis. Additionally, the anti-bacterial and fungal activity is compared by synthesizing various metal ferrites such as MnFe2O4, ZnFe2O4, and Fe3O4. The 50wt% MZF/rGO nanocomposite exhibits significantly high antibacterial activity. However, 10wt% MZF/rGO nanocomposite shows good antifungal activity than Fe3O4, MnFe2O4, ZnFe2O4, MnZnFe2O4, 50wt%, and 80wt% MZF/rGO nanocomposites. These findings suggest that the prepared ferrite nanocomposites hold promise for microbial inhibition.

“…Photocatalytic degradation has been an effective way to decompose various organic pollutants in wastewater because of its low cost and long security. − So far, many semiconductors have been investigated to be photocatalysts, such as metal oxide and sulfides. − However, the high recombination rate of photogenerated carriers (electrons or holes) and the large band gap reduce their photocatalytic efficiency. To suppress the recombination and enhance the absorption of sunlight, one of the most promising approaches is to construct heterostructure with different semiconductors. − A lot of heterojunctions have a good degradation effect and cycle performance in photocatalytic reactions, such as CdO/Al 2 O 3 , CoS/Ag 2 WO 4 , Bi 6 Cr 2 O 15 /Co 3 O 4 , MnS/Ag 2 WO 4 , and Bi 2 S 3 /KTa 0.75 Nb 0.25 O 3 heterostructures …”

The binary type II α-Bi 2 O 3 /Bi 12 TiO 20 heterojunction composite was successfully obtained by a simple hydrothermal process. The pH value and the Bi/Ti molar ratio were the key to form the α-Bi 2 O 3 /Bi 12 TiO 20 heterojunction. The α-Bi 2 O 3 nanobelts intertwined with the Bi 12 TiO 20 nanobelts to form a cross-shaped structure in the composite. The obvious red-shift can be detected in Raman spectra. UV−vis DRS also revealed that the effectively reduced band gap of the heterojunction composite led to sunlight absorption in a larger range. Meanwhile, the photocurrent responses and the EIS demonstrated that the combination of Bi 12 TiO 20 and α-Bi 2 O 3 significantly promoted the separation of photogenerated electron−hole pairs and suppressed their recombination, which was also confirmed by PL analysis. Furthermore, photocatalytic degradation experiments proved that the α-Bi 2 O 3 / Bi 12 TiO 20 heterojunction composite had excellent catalytic performance under visible light, whose rate constant value (k) was about 2.0 times that of pure α-Bi 2 O 3 and 4.5 times that of pure Bi 12 TiO 20 samples. A possible photocatalytic mechanism of α-Bi 2 O 3 /Bi 12 TiO 20 was also proposed based on p−p and type II heterojunction. It was concluded that the heterojunction structure markedly promoted the migration and separation of carriers to enhance its photoactivity.
