Abstract

In the first step, CoFe2O4 nanostructures were synthesized via a facile precipitation method without using any surfactant. The CoFe2O4-TiO2 nanocomposites were then prepared using the sol–gel method. The silver nanoparticles were produced by reducing silver nitrate (AgNO3) with sodium borohydride (NaBH4). By adding a reducing agent, CoFe2O4–TiO2–Ag was produced by a simple precipitation method. The prepared products were characterized by X-ray diffraction and scanning electron microscopy. The vibrating sample magnetometer shows the ferromagnetic property of ferrite nanostructures. The photocatalytic behavior of the CoFe2O4–TiO2–Ag nanocomposites was evaluated using the degradation of three dyes (acid violet, methyl orange, and acid blue) method ultraviolet light irradiation. The results showed a nanocomposite with an applicable magnetic and photocatalytic performance.
