Abstract

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.
