“…Beside the ability to absorb photons, the reusability, recyclability, low cost, chemical stability and high corrosion resistance are important factors in the selection of photocatalysts [57]. The crystallite size, surface area, band gap, cations distribution among tetrahedral (A) and octahedral (B) sites and magnetic properties are influenced by the dopant type and amount [10,43].…”

“…Among them, nanosized Co ferrite received a lot of attention due to its remarkable mechanical and chemical stability, wear resistance, dielectric character, electrical conductivity and excellent magnetic properties such as high coercivity (H C ) and moderate saturation magnetization (M S ), high Curie temperature (T C ) and large magnetocrystalline anisotropy [8,9]. It also possesses some other unique characteristics such as good catalytic performance, small particle size, large surface area, narrow optical bandgap, non-toxicity and low production costs [10]. Depending on the composition, synthesis method and thermal treatment, Co ferrites have different structural, optical, electric, magnetic and biomedical properties [4,11].…”

“…The doping with different elements adjusts the properties of ferrites by changing the structure, crystallinity and elements distribution among tetrahedral (A) and octahedral (B) sites [10]. The dopant amount, valency, size and site preferences define the structural, electrical and magnetic properties of doped Co ferrites [12].…”

Engineered nanomaterials with tailored properties are highly required in a wide range of industrial fields. Consequently, the researches dedicated to the identification of new applications for existing materials and to the development of novel promising materials and cost effective, eco-friendly synthesis methods gained considerable attention in the last years. Cobalt ferrite is one of the nanomaterials with a wide application range due to its unique properties such as high electrical resistivity, negligible eddy current loss, moderate saturation magnetization, chemical and thermal stability, high Curie temperature and high mechanical hardness. Moreover, its structural, magnetic and electrical properties can be tailored by the selection of preparation route, chemical composition, dopant ions and thermal treatment. This chapter presents the recent applications of nanosized cobalt ferrites doped or co-doped with divalent transition ions such as Zn 2+ , Cu 2+ , Mn 2+ , Ni 2+ , Cd 2+ obtained by various synthesis methods in ceramics, medicine, catalysis, electronics and communications.

Because aniline is a persistent pollutant, a cost‐effective and efficient removal method is urgently needed. This study evaluates the synergistic effect of nickel doping in spinel zinc ferrite to enhance the photocatalytic performance of magnetic nanoparticles. Herein, X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET), differential reflectance spectroscopy (DRS), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray spectroscopy (EDX)/Map, and vibrating‐sample magnetometry (VSM) techniques were used to evaluate Ni0.25Zn0.75Fe2O4 MNPs synthesis by a sol–gel method. The produced nanoparticles have a surface area of 20.325 m2 g−1. At room temperature, the nanoparticles exhibit superparamagnetic characteristics and can be readily separated from the aqueous solution. The bandgap has been determined to be 1.83 eV using Tauc's plot. In addition, the photocatalytic activity of as‐prepared Ni0.25Zn0.75Fe2O4 MNPs for aniline degradation under visible light irradiation was examined. The photocatalytic results demonstrate that nickel‐doped zinc ferrite has high photocatalytic activity in aniline degradation. Additionally, Ni0.25Zn0.75Fe2O4 magnetic nanoparticles (MNPs) are highly magnetic in nature, which simplifies separation and repetitive reuse.
