Influence of yttrium and magnesium on the optical-magneto properties of ferrite nanoparticles and catalytic study for metal ligand synthesis

MgxY1-xFe2-xO4 (x = 0.2, 0.4, 0.6, 0.8, and 1.0) was synthesised using the sol-gel method and sintered for 2 h at 900 degrees C. The X-ray diffraction revels the firm increase in the lattice parameter (7.9-8.5 angstrom) with FCC crystal structure. The average particle size ranges from 30 to 20 nm. Field emission-scanning electron microscopy shows partially spherical morphology. The optical band gap energies calculated from ultraviolet-visible spectra of magnesium ferrites doped with yttrium ranged from 3.14 to 3.27 eV. The existence of all inserted elements in the MgxY1-xFe2-xO4 composition was confirmed by energy dispersive X-ray spectroscopy. The highly magnetic nanocrystals were examined, which showed an enhancement in magnetization and anisotropy constant. According to the BET analysis, the surface area ranges from 5.88 to 20 m2 g-1, the pore volume ranges from 0.02 to 0.09 cm3 g-1, and the pore diameter ranges from 4.6 to 6.6 nm. The development of a single-phase cubic spinel structure has been verified by X-ray diffraction and Raman spectroscopy. Five Raman modes that are active (A1g, Eg, and 3F2g) are visible in the Raman spectrum, which is consistent with the spinel structure. The catalyst MgxY1-xFe2-xO4 is used to convert p-carboxy n-phenyl maleimide into various metal complexes.
