“…As chemical methods for the elaboration of inorganic particles, it must be mentioned that sol-gel, precipitation/co-precipitation, or hydrothermal methods are often utilized. Between these chemical strategies, chemical precipitation is simple, less expensive, eco-friendly, allows an easy scale-up method, and assures the formation of homogeneous particles [ 31 , 32 ].…”

Our study is focused on optimizing the synthesis conditions for the in situ oxidation of Fe particles to produce Fe@Fe3O4 core–shell powder and preparation via co-precipitation of ZnFe2O4 nanoparticles to produce Fe@Fe3O4/ZnFe2O4 soft magnetic composites (SMC) through a hybrid cold-sintering/spark plasma-sintering technique. XRD and FTIR measurements confirmed the formation of a nanocrystalline oxide layer on the surface of Fe powder and the nanosized nature of ZnFe2O4 nanoparticles. SEM-EDX investigations revealed that the oxidic phase of our composite was distributed on the surface of the Fe particles, forming a quasi-continuous matrix. The DC magnetic characteristics of the composite compact revealed a saturation induction of 0.8 T, coercivity of 590 A/m, and maximum relative permeability of 156. AC magnetic characterization indicated that for frequencies higher than 1 kHz and induction of 0.1 T, interparticle eddy current losses dominated due to ineffective electrical insulation between neighboring particles in the composite compact. Nevertheless, the magnetic characteristics obtained in both DC and AC magnetization regimes were comparable to those reported for cold-sintered Fe-based SMCs.

“… 31 The average size of the ZF nanoparticles was found to increase with the increase in the calcination temperature from 400 to 900°C. 32 The particle size of ZF nanoparticles was found to increase with a reduction of microstrain of ZF nanoparticles at 300°C, 500°C 33 and 900°C 34 estimated by the Debye–Scherrer and Williamson-Hall (W-H) plot methods. MFe 2 O 4 (where M=Zn, Ni and Cu) nanoparticles with crystallite sizes ranging from 15 nm to 66 nm were prepared using extract of Aloe vera plant mixed with metal nitrates and iron nitrate and calcined from 600 to 900°C.…”

We report herein the synthesis of ZnFe 2 O 4 (ZF) nanoparticles via a simple and eco-friendly green route using lemon juice as a reducing agent and fuel. The effect of different calcination temperatures on the particle size and bandgap of grown ZF nanoparticles was investigated. The structural, morphological and optical properties of the synthesized nanoparticles were evaluated using synchrotron x-ray diffraction (S-XRD), field emission scanning electron microscopy (FE-SEM) and UV-visible diffuse reflectance spectroscopy (UV-Vis-DRS), respectively. S-XRD confirmed a spinel F-d3m phase in all four samples calcined at 350°C, 550°C, 750°C and 1000°C. The crystallite size calculated from the Debye–Scherrer equation showed an increase from 14 nm to 20 nm with the increase in calcination temperature. Williamson–Hall (W-H) analysis revealed an increase in the particle size from 16 nm to 21 nm and a decrease in the lattice microstrain from 0.913 × 10 −3 to 0.154 × 10 −4 with the increase in calcination temperature. The optical bandgap of the ZF nanoparticles obtained from UV-Vis-DRS decreased from 2.265 eV to 2.225 eV with the increase in calcination temperature. The ZF nanoparticles with tunable particle size, lattice microstrain and optical bandgap have potential application in ferrofluid, electromagnetic shielding, photocatalysis, hyperthermia, dye degradation and other areas.

A systematic investigation of Ni and Zn spinel ferrites preparation via oxalate route, involving a detailed characterization of synthesized precursors, in situ study of thermally induced decomposition reactions and analyses of the prepared ferrites is presented. Although the oxalate route in general is rather well known, the detailed investigations of the decomposition reactions of the well-characterized bimetal oxalate precursors have been mostly omitted by the authors. The formation of the solid solution, i.e., the incorporation of both metals into the single oxalate crystal structure, is essential for the subsequent decomposition reaction and synthesis of pure spinel ferrites. The optimally prepared precursor decomposes in a single reaction step at relatively low temperatures, evading the undesirable sintering, and allowing the preparation of microporous/mesoporous ferrites with relatively high BET areas.
