Abstract
At the first step CoFe2O4 nanostructures were synthesized via a facile precipitation method without using any surfactant and capping agent in solvent of water. Then cadmium sulphides with various doping metals (Ni, Co, Zn and Ag) were prepared. Finally metal doped CoFe2O4-CdS nanocomposites were made by a fast chemical procedure. The effect of concentration, temperature and precipitating agent on the morphology and particle size of the products was investigated. The prepared products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy. Vibrating sample magnetometer shows the ferromagnetic property of the ferrite nanostructures. The photocatalytic behaviour of CoFe2O4-CdS-metal doped nanocomposites was evaluated using the degradation of four azo dyes (acid black, acid brown, acid violet and acid blue) under ultraviolet light irradiation. The results introduce a nanocomposite with applicable magnetic and photocatalytic performance.
