Low Crystalline MoS2 Nanotubes from MoS2 Nanomasks for Lithium Ion Battery Applications

The properties of MoS2 are highly dependent on its structure, which in turn is controlled by the fabrication methods. Low crystalline MoS2 nanotubes have properties combined with the unique characteristics of nanotubes and highly active sites. However, the preparation of MoS2 nanotubes with the desired configuration remains a big challenge. A facile method for the preparation of MoS2 nanotubes with highly active sites is investigated by using in situ grown 3D molybdenum disulfide nanomasks. The low crystalline MoS2 nanotubes with high specific surface areas and active sites are promising catalytic, sensing, and electrochemical materials. The high-performance lithium storage of the as-produced MoS2 nanotubes has been demonstrated by the low crystalline MoS2 nanotubes. A specific capacity of 1253 mAh/g has been obtained by the as-produced MoS2 nanotubes at a current rate of 200 mAh/g after 150 cycles.
