Synthesis of Cu₂O/NiFe₂O₄ Magnetic Complex and its Application in Photocatalytic Degradation

In order to enhance the re-collecting ability of Cu2O, Cu2O/NiFe2O4 magnetic complex was synthesized in this paper. XRD patterns showed the prepared material was the complex of Cu2O and NiFe2O4. The saturation magnetization (Ms) of Cu2O/NiFe2O4 magnetic complex was 12.056emu/g. The Cu2O/NiFe2O4 magnetic complex was used for the decolorization of P-nitrophenol solution in a photocatalytic degradation reactor under the visible light irradiation. In this work, the Cu2O/NiFe2O4 magnetic complex is recycled for 3 times, and the decomposition rates are all above 60%. The XRD also showed that the Cu2O/NiFe2O4 complex was neither oxidized nor deoxidized in the photocatalytic degradation process. It can be concluded that the prepared Cu2O/NiFe2O4 complex can be recycled applied to photocatalytic degradation treatment.
