摘要

In this study, significant progress was made in developing CoFe2O4 and La-doped Co0.7Mg0.3Fe1.98La0.02O4 nanoparticles. Structural analyses by X-ray diffraction and FTIR spectroscopy confirmed the formation of a pure spinel phase, especially in the lanthanum-doped samples. The observed increase in the lattice parameter is consistent with previous reports on rare earth-doped ferrites, highlighting the effect of doping on the crystal structure. X-ray photoelectron spectroscopy verified the presence of all expected elements and their oxidation states. Morphological studies revealed hexagonal and spherical nanoparticles. Magnetic measurements demonstrated a significant effect of doping, altering saturation magnetization and coercivity. Photocatalytic performance was evaluated by degrading carbamazepine (CBZ) under simulated solar irradiation, showing remarkable results: the La-doped sample removed almost 86.08% of CBZ in 60 min and 93.71% in 120 min, compared to only 30.48% and 70.79% for the undoped sample at the same times. Complete removal was achieved within 3 h. These findings highlight the potential of these nanoparticles for diverse nanotechnology applications due to their optimized structural, magnetic, and photocatalytic properties.
