Spinel ferrite MFe2O4 (M= Cu, Ca, Mg, Ni, etc.) nanoparticles and their composites are a new promising materials because have shown their great interest in field of sensing, optoelectronics, catalysis and solar cells due to their unique physical and chemical properties differing from their bulk structures. Today, lots of CuFe2O4 nanomaterials have been synthesized by different methods including hydrothermal route and sol-gel combustion method and so forth. Nevertheless, there are hardly any results about photocatalytic activity of it. For this reason, optical properties is increased by preparing composite of it with other oxides. In this paper, CuFe2O4@CuO magnetic composite was synthesized by ultrasound method. The samples prepared were characterized by XRD, FT-IR spectroscopy, DRS and SEM images, VSM, and EDS-mapping. The catalytic activity of as-synthesized CuFe2O4@CuO was evaluated using the degradation of methylene blue. Furthermore, a possible reaction mechanism was discussed. Finally, the catalyst was used for effective degradation of MB in its solution, which indicated its potential for practical applications in water pollutant removal and environmental remediation.
