Magnetic CoFe2O4 and silver nanoparticles were synthesized via simple chemical reactions using precipitation method at temperature of 60 °C. The all obtained materials are in the range of nano-scale magnetic particles. The effect of different surfactants (anionic, cationic and neutral) on the morphology of the products was investigated. zeolite Y–Ag–CoFe2O4 nanocomposites were also prepared by so called “ship in bottle” procedure. Scanning electron microscopy, X-ray diffraction pattern, Fourier transform infra-red were used to study the structural and physical properties of CoFe2O4 nanoparticles. The magnetic properties of the product were also investigated using a vibrating sample magnetometer. The cobalt ferrite nanoparticles exhibit various ferromagnetic behaviours by changing in surfactants at room temperature. The photocatalytic behaviour of zeolite Y–Ag–CoFe2O4 nanocomposite was evaluated using the degradation of four various azo dyes aqueous solution under UV light irradiation. The results confirm that zeolite Y–Ag–CoFe2O4 nanocomposites are suitable materials with suitable performance in photo-catalytic applications.
