Structural, electrical and magnetic properties of cadmium substituted copper ferrite by sol–gel method

The heterogeneous photocatalytic desulfurization processes have been paid wide attention due to their effectiveness in removing the condensed organo-sulfur compounds. Such methods may gain greater consideration via utilizing the visible light in general and sun spectrum in particular. This research work aims to produce low sulfur diesel fuel through a catalyzed photochemical route using nanoparticles of CdO under the visible-light irradiation. Two various structures of CdO were prepared in this study by both the chemical precipitation and autoignition techniques. The structural and morphological characteristics of the obtained cadmium oxides were determined via different tools of analyzes. The production of a low sulfur diesel fuel was then investigated under various operating parameters, such as type of light source, catalyst-to-feed dosage, and reaction time. The effect of adding oxidizing agents at different concentrations on the desulfurization process was also studied. After the maximum sulfur removal had been detected under the optimum conditions, the ultimate removal of sulfur was attained through a subsequent solvent extraction step. A diesel fuel with a sulfur content of 45 ppm was acquired at the end of this research study. A total sulfur removal of 99.6 wt % was obtained because the original diesel fuel feedstock has an overall concentration of the sulfur compounds of 11 500 ppm.

This work is devoted to the systematic study of the optical and magneto-optical properties of sputter deposited CuFe2O4 thin films in the photon energy region between 2 and 5 eV using spectroscopic ellipsometry and magneto-optical Kerr spectroscopy. The spectral dependence of both the diagonal and off-diagonal elements of the permittivity tensor is determined. A complete picture about the electron transitions in CuFe2O4 is suggested in the frame of intervalence charge transfer and intersublattice charge transfer transitions. The effect of deposition conditions and post-deposition treatment in CuFe2O4 films upon the optical and magneto-optical properties is discussed.

“…As the Co 2+ concentration rises, the structure will be more nearby to inverse spinel type that in turn reduces the contribution of hopping and decreases the size [9]. The X-ray density (D x ) was computed from the values of lattice parameter (a) using the following formula [28][29][30][31]: where '8' represents the number of molecules in a unit cell of spinel lattice, 'M' is the molecular weight of composition, 'N' is the Avogadro's number and 'a' is the lattice parameter. It can be seen from Table 2, the X-ray density (D x ) increases with the increasing Co substitution in Ni Ferrites and it shows the densification of the material.…”

The synthesis of cobalt ferrites (Co x Fe 3-x O 4 ) materials with sympathetic size and tunable magnetic properties is used for the promising industrial and biomedical applications. Such cobalt ferrites nanoparticles have been employed by co-precipitation technique. XRD analysis revealed that the average crystallite size of synthesized powder is 9 nm using (311) peaks, and it has exhibited polycrystalline structure. FTIR spectroscopy showed the formation of ferrite phase with high-and low-frequency bands at 573 cm −1 and 455 cm −1 , respectively. The TEM images exposed that the materials have been well agglomerated along with spherical-shaped nanoparticles. EDX study confirmed the presence Co, O, Fe and C with stoichiometric composition and no more impurity detected in the spectrum. The VSM analysis revealed that the sample exhibits the hard magnetic materials. In addition, the magnetic anisotropy increases (19.05 → 344.84 erg/g) when Co is added with Fe 3 O 4 . EPR spectroscopy confirmed the ferromagnetic behavior of composites.
