Magnetic CuFe2O4 submicrospheres were prepared by solvothermal method, and then modified with triaminopropyltrimethoxysilane (APTMS) as the surface modifier. CuFe2O4@NH2@Pt composites were prepared by in-situ reduction with ethylene glycol after adsorption of Pt4+ ions. The morphology, structure and crystal morphology of the samples are characterized by transmission electron microscopy (TEM), energy dispersive X-ray spectrometer (EDX), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Ultraviolet visible spectrophotometer(UV?Vis) and vibration sample magnetometer (VSM). The catalytic activities of organic dye p-nitrophenol and inorganic dye potassium ferrocyanate are investigated as the target pollutants. The results show that the degradation rate of p-nitrophenol is about 99.9% within 6 min, and the degradation rate of potassium ferric cyanate is about 97% within 9 min.It provides ideas and methods for efficient and convenient treatment of water pollution.
