中文摘要：

采用FeOOH纳米棒为前驱体,通过层层自组装法及随后的热处理过程制备出α-Fe2O3-Ag复合纳米棒.采用透射电子显微镜（TEM）、高分辨透射电子显微镜（HRTEM）和电化学性能测试对样品的形貌、结构及电化学性能进行了表征.结果表明,Ag纳米颗粒均匀地分布在α-Fe2O3纳米棒的表面.作为锂离子电池负极材料,α-Fe2O3-Ag复合纳米棒表现出了较好的循环性能和较高的比容量.180个循环后,其比容量高达549.8 mA.h/g.

英文摘要：

Using FeOOH nanorods as precursors,α-Fe2O3-Ag hybrid nanorods were prepared through a novel layer-by-layer assembly and subsequent annealing approach.The morphology,structure and electrochemical performance of the products were characterized by transmission electron microscopy（TEM）,high-resolution transmission electron microscopy（HRTEM）,and electrochemical tests.It is indicated that numerous Ag nanoparticles are homogeneously distributed on the surface of α-Fe2O3 nanorod.When evaluated as an anode for Li-ion battery,the α-Fe2O3-Ag hybrid nanorods exhibit better cyclic performance and higher capacities.A high capacity of 549.8 mA·h/g can be retained after 180 discharge/charge cycles.
