The carbon wrapped magnetic nanosphere Fe 3 O 4 @C (∼300 nm) was prepared under simple hydrothermal conditions, and it served as the carrier of Rh nanoparticles (2‐3 nm), which acted as the highly efficient catalyst for reduction of nitro compounds, and reutilization of catalyst is convenient to achieve because the catalyst particles are magnetic. A scope of nitroarene derivatives were reduced to corresponding anilines in water, and the reactions completed in 10 min with nearly quantitative conversions and 100% selectivity. In addition, the abundant oxygen‐containing functionality on the carbon shell which can strongly binds the Rh‐NPs to offer extraordinary stability is investigated by using various techniques, including transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), X‐Ray Diffraction (XRD), and Fourier transform infrared spectrometer (FT‐IR).
