Original Article


In this study, we first examined nanoparticles of Fe3O4 structures synthesized as magnet cores using simple hydrothermal method without surfactant, and at the next stage, we have prepared Zn-doped cadmium sulfide as dual shell. Therefore, doped-metal nanocomposites Fe3O4–Cds were produced and characterized by a rapid chemical process. The effects of concentration, temperature, and sediment factor on the morphology and particle size of the products were studied. The structure and morphology of products were studied using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectrometer. A vibrating sample magnetometer was used to identify the ferromagnetic behavior of ferrite nanostructures. Also, to study the photocatalytic behavior of Fe3O4–Cds–Zn-doped nanocomposites, degradation of three azoic acids (acid black, acid blue, and methyl orange) was used under ultraviolet light. According to the results, the magnetic and photocatalytic function of these nanocomposites is clearly evident.
