A visible active CuFe2O4/MoS2 magnetic nanocomposite was successfully synthesized via hydrothermal technique. The synthesized photocatalysts were perused by X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscopy, Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–vis diffuse reflectance/absorbance spectroscopy and Vibrational sample magnetometer measurements. Also, the photocatalytic efficiency was investigated by photocatalytic degradation of Rhodamine B under visible light illumination. As a result, CuFe2O4/MoS2 was showed excellent reusability through magnetic separation and its degradation rate of Rhodamine B as high as 98.5%. In addition, the mechanism of the Rhodamine B degradation elucidated that•O2 radicals had the most significant role in the photocatalytic proceses for CuFe2O4/MoS2 composite.
