Highlights: • The Cu-Fe{sub 3}O{sub 4}@GE composite was prepared by one-step solvent–thermal method. • The Cu-Fe{sub 3}O{sub 4}@GE composite exhibited the highest catalytic activity with excellent stability. • The Cu-Fe{sub 3}O{sub 4}@GE composite was magnetically separable. - Abstract: In this work, the Cu-Fe{sub 3}O{sub 4}@GE composite was prepared easily by a one-step solvent–thermal method, which achieved the formation of Cu nanoparticles (Cu NPs), Fe{sub 3}O{sub 4} nanoparticles (Fe{sub 3}O{sub 4} NPs) and reduction of GO simultaneously. The morphology and structure of the composite was fully characterized by means of X-ray diffraction (XRD), Fourier transformed infrared (FTIR) spectroscopy, transmission electron microscopy (TEM). The time-dependent adsorption spectra of the reaction mixture was measured by UV–vis absorption spectroscopy. The results demonstrated that the Cu NPs and Fe{sub 3}O{sub 4} NPs were densely and evenly deposited on the graphene (GE) sheets. It was found that the Cu-Fe{sub 3}O{sub 4}@GE composite exhibited high catalytic activities on the reduction of p-nitrophenol to p-aminophenol. Furthermore, the composite catalyst can be easily recovered due to its magnetic separability and high stability.
