A nanohybrid based on ZnFe2O4 nanospheres and graphene nanosheets (ZnFe2O4/G) has been synthesized by a facile one-pot in situ solvothermal route. The results show that the formation of ZnFe2O4 and the reduction of graphite oxide take place simultaneously during the solvothermal reactions. Spheric ZnFe2O4 nanoparticles with a size of 100-200 nm are confined in between the graphene sheets, forming a unique hybrid nanostructure. The electrochemical measurements have shown that the ZnFe2O4/G hybrid exhibits improved electrochemical Li-storage properties compared with bare ZnFe2O4, due to the combined buffering, confining and conducting effects of the in situ introduced graphene nanosheets.
