摘要：

NiCe2O4 nanoparticles on graphene oxide hold a promising nanostructure material for a wide range of applications due to their tunable physical/chemical properties. Herein, it is reported a simple strategy to synthesize nickel-cobalt nanoparticles loaded on reduced graphene oxide (rGO) to form an integrated nanostructure. The thermal treatment of NiCe2O4 precursor@rGO resulted in the formation of spinel NiCe2O4 nanoparticles of about 10 nm directly on rGO nanoplatform. Magnetic characterization of non-treated and thermally treated samples was evaluated showing that NiCe2O4@rGO exhibits superparamagnetic behavior with a maximum occurring at 20 K.
