In this paper, ferromagnetic Fe2O3/Mn2O3 nanocomposites (Fe@Mn-1 and Fe@Mn-2) were synthesized and characterized using Fourier transform infrared (FT-IR) spectroscopy, X-ray powder diffraction (XRD), vibration sample magnet (VSM) and transmission electron microscope (TEM). All results confirmed that the successfully synthesis of Fe@Mn-1 and Fe@Mn-2 nanocomposites with ferromagnetic property at room temperature with magnetic saturation of 6.48 and 9.24 emu/g, respectively. In addition, photocatalytic activities of Fe@Mn-1 and Fe@Mn-2 were studied on the degradation of methylene blue (MB) by applying H2O2 under visible light irradiation. The effect of important parameters on the MB degradation were evaluated and the results exhibited the best photocatalytic activity within 45 min owing to the Fe@Mn-1 (98%) and Fe@Mn-2 (97%), due to their very small crystallite sizes.
