- 2013年第19卷 
利用水热法合成出分散的球形纳米Fe3O4，探讨含十二烷基三甲基溴化铵表面活性剂合成样品形貌和尺寸. 测试表明Fe3O4纳米球呈现出优越的倍率性能和循环性能.Dispersed spherical Fe3O4 nanoparticles were synthesized by a hydrothermal method. The influences of odecyl trimethyl ammonium bromide (DTAB) concentration on the morphology and particle size of the as-prepared Fe3O4 were studied. Electrochemical performance of the as-prepared sample as anode materials of lithium ion battery was investigated. It is found that the as-prepared sample exhibits superior rate performance and cycle performance. The nano-sized materials provide structural stability and favor the transfer of lithium ions.
