MoS2 nanosheet arrays supported on hierarchical porous carbon with enhanced lithium storage properties

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(1305.5 mA h g^-1 at 100 mA g^-1),excellent rate capability (438.4 mA h g^-1 at 1000 mA 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.
