S,N co-doped carbon nanotubes decorated with ultrathin molybdenum disulfide nanosheets with highly electrochemical performance

Abstract

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/MoS₂), is now reported. The number of nanosheets for MoS₂ 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/MoS₂ nanotubes show a high specific capacity of around 1500 mA h g⁻¹ at the current density of 50 mA g⁻¹, excellent cycling stability up to 750 cycles at the current density of 1 A g⁻¹, and superior rate performance.
