“…Additionally, a proton and a superoxide radical anion combine to form the hydroperoxyl radical ( ). The positive hole can oxidize hydroxyl radicals from hydroxide ions or water molecules that have been adsorbed on the nanoferrite particles surface (Gaikwad et al, 2019). Usually, the resultant radical could react with organic dye to form a variety of intermediates, which when mixed with nitrate ions, mineralize to yield carbon dioxide, water, and inorganic nitrogen.…”

Cobalt based nanoferrites Co 1 − x Cu x Ce y Fe 2−y O 4 Where nano ferrites produced through citrate gel auto combustion technique and their structural and topographical studies were inspected through x-ray diffraction technique and eld emission scanning electron microscope. The structural analysis con rms the prepared nano ferrites having single-phase cubic spinel, along Fd3m space group. Crystalline size of the synthesized samples found 20-26 nm calculated by Debey Scherrer formula. Catalytic activity of the samples con rmed by dye degradation studies of methylene blue and acid red dye degradation. Magnetic behavior of the materials measured by a vibrating sample magnetometer, saturation magnetization gradually decreases as increasing Cu and Ce content and found to be 26 to 18 emu/gm. Electrical properties were measured by LCR meter.

“…The grain size of the sample is usually calculated by the linear intercept method using equation (10). 35) (10) where L, M, and N are the total length of the test line, magnification, and number of intercepts, respectively. The morphology and size of particles were influenced by the Crdoping content and calcination temperature, and the size ranged from 0.190.23 µm.…”

“…Among cubic spinel ferrite materials, zinc ferrites are unique and technologically important, and find a variety of applications in water splitting, biomedicine, photocatalysts, transformer cores, microwave technology, magnetic recording media, and gas sensors. [9][10][11][12][13] The general formula of the cubic spinel structure is AB 2 O 4 , where "A" is a bivalent metal ion and "B" is a trivalent metal ion. The spinel ferrite crystal structure consists of a cubic closed arrangement of oxygen ions with 8 tetrahedral (A-site) and 16 octahedral (B-site) interstitial sites in the unit cell.…”

Chromium-doped zinc ferrite nanoparticles with the general formula Cr y ZnFe 2-y O 4 (y = 0, 0.025, 0.05, 0.075, and 0.1) were synthesized by a surfactant-assisted chemical co-precipitation route using metal nitrate salt precursors. The phase purity and structural parameters were determined by powder X-ray diffraction. The concentration of Cr 3+ doped into ZnFe 2 O 4 (ZF) noticeably affected the crystallite size, which was in the range of 22 nm to 36 nm, and all samples showed a single cubic spinel structure without any secondary phase or impurities. The lattice parameter, X-ray density, and skeletal density increased with an increase in the Cr-doping concentration; on the other hand, a decreasing trend was observed for the particle size and porosity. The influence of Cr 3+ substitution on ZF magnetic properties were studied under an applied field of 15 kOe. The overall results revealed that the incorporation of a small amount of Cr dopant changed the structural, electrical, and magnetic properties of ZF.

“…They have the advantage of small eddy current loss. Ferrites have wide ranges of applications; they can be used in biomedicine, magnetic storage media, catalysts, radio energy transmission systems and environmental governance [3,4]. In recent years, compared with bulk materials, nanomaterials have become the focus of many researchers because of their unique applications [5].…”
