Abstract BACKGROUND To address water scarcity and promote sustainable resource management, more efficient cost‐effective treatment solutions are necessary. Particularly, pathogens in drinking a topic of growing concern. One promising technology is the use photocatalytic nanoparticles activated by visible light as antibacterial agents. This study focuses on characterization properties Co–Zn ferrite nanocatalysts, tested against Escherichia coli . RESULTS The Co x Zn 1− Fe 2 O 4 ( = 0, 0.1, 0.4 0.6) ferrites were synthesized co‐precipitation method. Structural, morphological optical analyses confirmed that these have cubic spinel structure, with sizes around 10 nm, band gap energies suitable for activation (1.4–1.7 eV). efficacy E. was compared their performance employing phenol organic pollutant model (highest degradation 0.6). Specifically, capacity evaluated comparing ability bacteria to grow after being incubated under dark. It found lower cobalt content 0 0.1) significantly reduced bacterial culturability light. Transmission Electron Microscopy analysis revealed caused secrete biofilm, potentially offering some protection nanoparticles. CONCLUSION ZnFe show highest effect amongst those tested. attributed combined action 2+ ion release Furthermore, might inhibit protective biofilm secretion, leading higher effects. © 2024 Author(s).
