Abstract
Magnetic photocatalyst ZnO/nickel-zinc ferrite powders were synthesized by two-step method: First ,nickel-zinc ferrite powders were prepared by coprecipitation method and then ZnO /nickel-zinc ferrite composite powders were prepared by the homogeneous precipitation method. The as-prepared sample was characterized by X-ray Diffraction (XRD), and Transmission Electron Microscopy (TEM), the photocatalysis of the catalyst was evaluated with methylene blue as decomposition substance and the photocatalytic activity of the material has been tested on decomposable substrate under visible-light in the magnetic photocatalytic wastewater treatment reactor. The results demonstrate that the magnetic photocatalyst ZnO/nickel-zinc ferrite powders exhibit highly efficient visible-light-driven photocatalytic activity, the degradation rate of methylene blue is 84%.
