采用一步水热法合成了Fe 3 O 4/SnO 2/rGO三元复合材料。在该复合材料中，rGO作为一个导电的和强大的矩阵，Fe 3 O 4和SnO 2纳米粒子均匀地负载在rGO纳米片上没有聚集，由于空间限制效应的同时成核和生长的Fe 3 O 4和SnO 2纳米晶体.作为锂离子电池负极材料，Fe 3 O 4/SnO 2/rGO纳米复合材料在200 mA g − 1的电流密度下首次循环的可逆容量为947 mAh g− 1，200次循环后仍保持831 mAh g− 1。与对照实验中得到的FeOx/rGO和SnOx/rGO的二元对应物相比，Fe 3 O 4/SnO 2/rGO的循环性能和倍率性能显著改善，这是由于三元复合材料中的协同效应增强了结构稳定性和电荷和Li+转移动力学。
A ternary composite of Fe3O4/SnO2/rGO has been synthesized via a facile one-step hydrothermal method. In the composite, rGO serves as a conductive and robust matrix, Fe3O4and SnO2nanoparticles are uniformly loaded on the rGO nanosheets without aggregation, due to the space-confine effect of the simultaneous nucleation and growth of Fe3O4and SnO2nanocrystallites. As an anode material for lithium-ion batteries, the Fe3O4/SnO2/rGO nanocomposite exhibited a reversible capacity of 947 mAh g−1at a current density of 200 mA g−1in the first cycle, and maintained 831 mAh g−1after 200 cycles. The cyclic performance and rate capability of the Fe3O4/SnO2/rGO are markedly improved compared with the binary counterparts of FeOx/rGO and SnOx/rGO obtained in the control experiment, as a result of enhanced structural stability and kinetics for charge and Li+transfer due to the synergetic effect in the ternary composite.
