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.
