摘要

MoS2 nanosheet arrays supported on hierarchical nitrogen-doped porous carbon (MoS2@C) have been synthesized by a facile hydrothermal approach combined with high-temperature calcination.The hierarchical nitrogen-doped porous carbon can serve as three-dimensional conductive frameworks to improve the electronic transport of semiconducting MoS2.When evaluated as anode material for lithium-ion batteries,the MoS2@C exhibit enhanced electrochemical performances compared with pure MoS2 nanosheets,including high capacity (1305.5mAhg-1 at 100mAg-1),excellent rate capability (438.4mAh g-1 at 1000mA g-1).The reasons for the improved electrochemical performances are explored in terms of the high electronic conductivity and the facilitation of lithium ion transport arising from the hierarchical structures of MoS2@C.
