“…A new peak at 445 cm −1 was observed, which was due to the stretching of the Co-O and confirmed the existence of Co atoms in the Ni0.5Zn0.5Fe2O4 lattice. When the sample was sintered at 800°C, the stretching vibrations induced by the C-O bond with peaks around 1091 -1143 cm −1 were noticeably weakened which is similar to the observation reported by Thakur et al 2016. The UV-vis DRS absorption spectra of the NZF and Co−NZF over the wavelength range of 200-800 nm are represented in Fig.…”

“…In both samples, several grain surfaces have hexagonal shapes and distorted edges, which is the basic crystal cell unit of ferrites (Thakur et al 2016;Mustafa and Oladipo 2021). The presence of metal ions with compositions consistent with the predicted stoichiometry of Ni0.5Zn0.5Fe2O4 was verified by energy-dispersive X-ray spectroscopy (EDX) analysis of the samples (Fig.…”

“…The magnetization results revealed ferromagnetic activity which is common for soft magnetic material (Džunuzović et al 2015). NZF's saturation magnetization (Ms) is 79.28 emu g −1 , which is less than Co−NZF's (85.94 emu g −1 ); while these values are higher than the 57−78 emu g −1 stated previously (Džunuzović et al 2015;Thakur et al 2016 220), ( 311), ( 222), ( 400), ( 422),…”

“…As previously stated, the tetrahedral and octahedral sites are strongly preferred by Zn and Ni atoms, respectively. Fe 3+ cations, on the other hand, can occupy octahedral and tetrahedral sites (Thakur et al 2016;Debnath et al 2021). According to Fig.…”

Here, metronidazole (MZ) antibiotic degradation and bactericidal efficacy of Co–Ni0.5Zn0.5Fe2O4 (Co–NZF) with and without photoactivation by UV light is reported as a viable cost-competitive water disinfection solution. Co–NZF has a total pore volume of 0.298 cm3 g− 1, a specific surface area of 70.2 m2 g− 1 and sufficiently high magnetic properties (80.35 emu g− 1). After 360 min of UV–assisted irradiation at pH 3, 10 mg Co–NZF, and 4 mM H2O2, the maximum MZ degradation was reached (92.8%). The adsorption result of 10 mg Co–NZF in the dark for 12 h resulted in 70.2% MZ removal, whereas MZ self-degradation was significantly minimal in a blank trial. In the presence of interfering anions and very high molecular weight tylosin antibiotic, Co–NZF maintained 51.7–75.4% degradation efficiency. The effect of the Co–NZF dosage on the viability of Staphylococcus aureus and Escherichia coli strains showed that 15 mg of the catalyst was sufficient to cause bactericidal activity after 180 min in the presence of UV light, while 25 mg is needed under dark conditions. In addition, when compared to Escherichia coli strains, Co–NZF showed higher inhibition against Staphylococcus aureus in time-kill experiments under dose variation.

Ferrites are of great interest for both fundamental science and technological applications due to their outstanding physical, chemical, and magnetic properties. Among various ferrites, Mg‐Zn ferrites is one of the best magnetic materials for researchers due to their unique properties such as high electric resistivity, Curie temperature, low coercivity, low eddy current, dielectric losses, low cost, and better environmental stability. This makes ferrites suitable for many applications such as power transformers, microwave devices, computer memories, logic devices, recording heads, loading coils, antenna rods, color monitoring tubes, telecommunications, hyperthermia, and so forth. Mg‐Zn ferrite nanoparticles have gained increased interest for many applications such as catalysts, antimicrobial potential, and sensors for the detection of combustible gases (CH4, CO, and CO2). In this brief review, the strategies used in the synthesis of Mg‐Zn ferrite nanoparticles are summarized. The different structural, morphological, magnetic, and electric properties of these ferrites are analyzed.
