A comprehensive experiment for the preparation and property study of heterogeneous magnetic Fenton catalyst was designed. A core-shell structured Fe3O4/ α-Fe2O3 nanocomposite was synthesized. The morphology,component and structure were characterized by SEM,XRD,TEM and FTIR. To evaluate the catalytic properties of the as-prepared magnetic Fenton catalyst,the catalytic decolorization experiment of methylene orange aqueous solution was carried out.The results showed the core-shell structured Fe3O4/ α-Fe2O3 nanocomposite was obtained. The as-prepared nanocomposite was about 50 - 80 nm in diameter. The new catalyst has the advantages of excellent catalytic activity toward methylene orange and available for recycling as for its good magnetic property. The experimen
