Abstract

Cobalt ferrite with a spinel structure is an important magnetic material.‌ These materials have interesting electrical and magnetic properties with high thermal and chemical stability. In this study, ferritic compound CO1-xMgxFe2O4 was prepared with different values of X 0.0, 0.2, 0.4, 0.6 and 0.8 using a sol-gel combustion method. The crystalline structure of the prepared samples was studied using an X-ray diffraction device (XRD). The particle Morphology was studied using scanning electronic microscope (SEM). The magnetic properties of the samples were investigated by a VSM Magnetized Magnetometer device. Also, the photocatalytic activity of nanostructures prepared for the destruction of organic contamination was studied using ultraviolet-spectrometer spectroscopy. The powder diffusion pattern showed that the produced powders had a spinel crystal structure and no impurities were observed. Investigating the magnetic properties of the samples showed that, by increasing the amount of magnesium, the nature of the sample varies from hard to soft ferromagnetic. Photocatalytic results showed that these materials are capable of destroying organic colors in the presence of visible light.
