The properties of MoS 2 are highly dependent on its structure, which in turn is controlled by the fabrication methods. Low crystalline MoS 2 nanotubes have properties combined with the unique characteristics of nanotubes and highly active sites. However, the preparation of MoS 2 nanotubes with the desired configuration remains a big challenge. A facile method for the preparation of MoS 2 nanotubes with highly active sites is investigated by using in situ grown 3D molybdenum disulfide nanomasks. The low crystalline MoS 2 nanotubes with high specific surface areas and active sites are promising catalytic, sensing, and electrochemical materials. The highperformance lithium storage of the as-produced MoS 2 nanotubes has been demonstrated by the low crystalline MoS 2 nanotubes. A specific capacity of 1253 mAh/g has been obtained by the as-produced MoS 2 nanotubes at a current rate of 200 mAh/g after 150 cycles.
