MoS_2 nanosheet arrays supported on hierarchical nitrogen-doped porous carbon(MoS_2@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 MoS_2.When evaluated as anode material for lithium-ion batteries,the MoS_2@C exhibit enhanced electrochemical performances compared with pure MoS_2 nanosheets,including high capacity(1305.5 mAhg~(-1) at lOOmAg~(-1)),excellent rate capability(438.4mAhg~(-1) at 1000mAg~(-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 MoS_2@C.
MoS_2 nanosheet arrays supported on hierarchical nitrogen-doped porous carbon (MoS_2 @ 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 MoS_2.When as an anode material for lithium-ion batteries, the MoS_2 @ C exhibit enhanced electrochemical performances compared with pure MoS_2 nanosheets, including high capacity (1305.5 mAhg -1 at 100 mAg -1) excellent rate capability (438.4 mAhg -1 at 1000 mAg -1). The reasons for the improved electrochemical performances are explored in terms of the high electronic conductivity and facilitation of lithium ion transport arising from the hierarchical structures of MoS 2 @C.
