▎ 摘　　要

CoFe2O4-graphene hybrid materials (CFGHs) were synthesized by a simple one-step combustion method. The structures, morphologies and magnetic properties were characterized by X-ray diffraction, transmission electron microscopy, Raman spectrometry, vibrating sample magnetometry, and photoluminescence. The morphologies of CFGHs show that CoFe2O4 nanoparticles were anchored onto the surface of graphene sheets. After the combustion synthesis, graphene oxide sheets were not oxidized, but reduced. CFGHs exhibit ferromagnetic behaviors and can be magnetically separated. Compared with pure CoFe2O4, CFGHs show improved photodegradation performance. The mechanism of enhancement in photodegradation performance is discussed in detail. (C) 2013 Elsevier B.V. All rights reserved.
