In this study CoFe2O4 nanostructures were synthesized via a facile precipitation method without using any surfactant and capping agent in solvent of water. Then Zinc sulphides with various doping metals (Ni, Co , Cu and Ag) were prepared. Finally metal doped CoFe2O4-ZnS nanocomposites were made by a fast chemical procedure. The prepared products were subjected to various analyses of structural (XRD), optical (UV–visible) , the formation of bonds using the (FTIR) spectrometry and surface layer morphology via SEM. Vibrating sample magnetometer shows the ferromagnetic property of the ferrite nanostructures. The photocatalytic behaviour of CoFe2O4-ZnS-metal doped nanocomposites was evaluated using the degradation of three azo dyes (acid violet, acid blue, methyl orange) under ultraviolet light irradiation. The results introduce a nanocomposite with applicable magnetic and photocatalytic performance.Vibrating sample magnetometer shows the ferromagnetic property of the ferrite nanostructures.
