A facile route for the synthesis of a type of composite nanotube, namely S,N co-doped carbon nanotubes decorated with molybdenum disulfide nanosheets (CP/MoS), is now reported. The number of nanosheets for MoS can be easily tuned by changing the templates with different ratios of N and S. When evaluated as an anode material for lithium-ion batteries, the CP/MoS nanotubes show a high specific capacity of around 1500 mA h g at the current density of 50 mA g, excellent cycling stability up to 750 cycles at the current density of 1 A g, and superior rate performance.
现报道了一种合成复合纳米管的简便方法，即 S，N 共掺杂碳纳米管上修饰二硫化钼纳米片（CP/MoS）。通过改变具有不同 N 和 S 比例的模板，可以轻松调节 MoS 的纳米片数量。当作为锂离子电池的阳极材料进行评估时，CP/MoS 纳米管在 50 mA g 的电流密度下具有约 1500 mA h g 的高比容量，在 1 A g 的电流密度下高达 750 次循环的优异循环稳定性，以及出色的倍率性能。
