This study aims to improve the influence of copper substitution on the structural, magnetic, morphological, and antimicrobial properties of zinc nanoferrites. Copper-substituted zinc nanoferrites were synthesized using the sol-gel auto-combustion method and thermal calcination at 425 °C. X-ray diffraction patterns detected the cubic phase of Zn_1<i>−x</i>Cu_<i>x</i>Fe₂O₄ (where <i>x</i> = 0.2, 0.4, and 0.6) powders. The obtained crystallite sizes are found to range from 23.883 to 24.718 nm. The pictures taken with a field emission scanning electron microscope show that the particle size grows from about 28.762 nm (<i>x</i> = 0.2) to about 39.025 nm (<i>x</i> = 0.6) with a copper substitution. FTIR of the studied samples shows two strong absorption bands around 600 and 400 cm⁻¹. This proves that a single-phase cubic spinel structure has formed. The magnetization investigations indicate increased saturation magnetization from 20.5482 to 58.7671 emu/g with increasing copper concentration. An elevation in mean Zeta potential values was noted with an augmentation in cu²⁺ substitution. It was also found that the hydrodynamic diameter size of the prepared nanoferrites increased from 243.2 to 314.2 nm with increasing copper substitution. Zn_1<i>−x</i>Cu_<i>x</i>Fe₂O₄ nanoferrites show promising inhibitory effects against four harmful bacteria: <i>Streptococcus aureus</i>, <i>Staphylococcus aureus</i>, <i>Escherichia coli</i>, and <i>Pseudomonas aeruginosa</i>. All copper treatments exhibited appropriate antibacterial properties. Nonetheless, the therapy with <i>x</i> = 0.2 proved the most efficacious. For <i>E. coli</i> (34.12 ± 0.28 mm), a Gram-negative bacterium, the optimal treatment was <i>x</i> = 0.2. In contrast, the most effective treatment for Staphylococcus aureus (34.11 ± 0.38 mm), a Gram-positive isolate, was <i>x</i> = 0.2 with 2 µg/mL. Our discovery paves the road for integrating copper-substituted zinc nanoferrites in biomedical applications, particularly against human pathogenic bacteria.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"114 3","pages":"841 - 856"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterization techniques, including XRD, TEM, XPS, and Raman spectroscopy, confirmed the successful incorporation of Ti into the CeO₂ lattice, leading to the formation of pure CeO₂ nanoflowers with cubic structure and an increase in oxygen vacancies. The optical band gap of the doped nanoflowers decreased from 3.27 to 3.07 eV. Room temperature ferromagnetism was observed in Ce_1-xTi_xO₂ nanoflowers (x = 0.01, 0.03, and 0.05). Notably, the x = 0.05 composition exhibited a remarkable 376% increase in ferromagnetism, reaching 55 × 10⁻³ emug⁻¹ at 15 kOe. This ferromagnetism is likely attributed to the oxygen vacancies created by doping, which trap charges and lead to the formation of F-centers. These F-centers then interact with impurity atoms, enhancing the magnetic properties. Increased Ti-doping resulted in a noticeable quenching of photoluminescence intensity, indicating improved charge carrier separation. This enhanced separation contributed to the photocatalytic activity of the synthesized samples, which was assessed by methylene blue degradation under UV light. The sample with x = 0.05 exhibited the highest photocatalytic activity.
