主　　题：FexOy-CeO2 composite 3D micro/nanostructures degradation of hexachlorobenzene 

摘      要：A micrometer-sized nanostructured,magnetic,ball-like FexOy-CeO2 composite was synthesized through an ethylene-glycol mediated *** synthesized samples were characterized by scanning electron microscopy combined with energydisperse X-ray analysis,transmission electron microscopy and X-ray powder *** the synthesis system,polyethylene glycol (PEG) and urea were found to play significant roles in the formation of the micrometer-sized spherical architecture of the *** details of morphology and particle size could be changed with the initial concentration of Fe(NO3)3-9H2O and Ce(NO3)3-6H2O as the *** magnetic FexOy-CeO2 composite with a similar morphology was readily obtained by calcination from the *** characterization of transmission electron microscopy showed the calcined ball-like architecture was a highly porous structure consisting of many *** of the micrometer-sized nanostructure and the multi-components as well as the magnetism,the as-obtained FexOy-CeO2 composite showed better activity and potentially easy recovery for the harmless degradation of hexachlorobenzene (HCB).
