چکیده انگلیسی
Magnetically separable CoFe2O4/ZnO and CoFe2O4/ZnO/Ag nanocomposites were successfully synthesized using CoFe2O4 nanoparticle as core by a simple precipitate route. The structural, morphology and functionality of prepared samples were analyzed using X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, diffuse reflectance spectroscopy, and vibration sample magnetometer. The micro-structural study approved that the synthesized nanoparticles have spherical morphologies with average particle size between 30 and 47â¯nm. The influence of nanocomposites on the acid violet and acid brown degradation was investigated under ultraviolet light. The CoFe2O4/ZnO nanocomposite showed enhanced photocatalytic activity, achieving acid violet and acid brown degradation efficiency of 76% and 63% respectively, rather than other samples. The increase in photocatalytic activity of CoFe2O4/ZnO hybrid may be associated with the formation of a suitable internal structure between CoFe2O4 and ZnO. Magnetic measurement indicated that CoFe2O4/ZnO is ferromagnetic with the magnetization saturation value of 25â¯emu/g, which is suitable for magnetic recovery by using an external magnetic field.
