“…Hence, compounds have not been deprived of stoichiometry in the formation of oxide from its primary materials. Therefore, it appears that the potential ratios of transition metals Mg, Cr, Fe, and Ce are in great agreement with the EDS analysis that confirms that sol-gel technology is capable of producing oxides of high elemental similarity [26] (see Figure 4).…”

The spinel sequenced structure is prepared using the sol-gel technique to study the influence of cerium metal onto the structure, magnetic, and morphological properties of MgCr 0.5-x CexFe 1.5 O 4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) ferrites. The formation of a magnesium ferrite phase is confirmed for all prepared samples by using X-ray diffraction, and the structural properties are studied. It is found that the lattice constant increases with the increase in the cerium content, which ranges between (8.35 and 8.45) Å, also found the crystallite size ranges between (8.25 and 17.51) nm. On the other hand, the images of SEM appear existence of agglomeration, distinct nanoparticles of the samples with not uniform distribution of broader grain size. EDX analysis confirms there are no other elements as impurities are detected in synthesized samples. Magnetic measurements by VSM made at room temperature reveal that the magnetization value decreases to x = 0.01 and then increases with the content of Ce 3+ ions. The magnetic nature of the doping samples does not play a major role in determining the final magnetic properties of the compound. Rather, the cation distribution is an important parameter. These properties reveal the super-magnetic nature of the cerium-saturated Mg nanoparticles and may be convenient for catalysts and moisture sensors.

The present wet chemical route overcome all drawbacks of conventional processes and produce ultrafine, homogeneous reproducible ferrite powders using aqueous solutions of nitrate salts of constituent ions. The study is investigated for the application of system MgFe 2-x Cr x O 4 (0.0 B x B 1.0) in photo decoloration and degradation of MO, MR and CR dyes. The precipitation methods always have the disadvantage that the stoichiometry of the precipitate may not be exact if one or more ions are left in solution. The sol-gel route overcomes this because the reactants never precipitate out. The basic aim of this study is photocatalytic performance of synthesized compounds for effective degradation of dyes under severe conditions.
