英文摘要	fe3o4-sno2-graphene ternary nanocomposite was firstly synthesized by using a gas-liquid interfacial synthesis approach. the as-prepared nanocomposite was characterized by x-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. the scanning electron microscopy and transmission electron microscopy characterization results indicate that fe3o4-sno2 nanoparticles were successfully deposited onto the surfaces of graphene sheets during the gas-liquid interfacial reaction process. the electrochemical performances were evaluated by using coin-type cells vs. metallic lithium. the fe3o4-sno2-graphene nanocomposite exhibits a high reversible specific capacity of 1198 mah g(-1) in the 115th cycle at a specific current of 100 ma g(-1) and good rate capability, even at a high specific current of 2000 ma g(-1), the reversible capacity is still as high as 521 mah g(-1). the good electrochemical performance of the fe3o4-sno2-graphene nanocomposite can be attributed to the synergistic effect existing not only between the graphene and metal oxides but also between the fe3o4 and sno2.
