Nanowire Templated CVD Synthesis and Morphological Control of MoS2 Nanotubes
Although the synthesis of molybdenum disulfide (MoS2) nanoparticle, nanosheet, and nanotube (NT) have been reported for years, the synthesis and morphological control of the few-layered MoS2 NT is still a great challenge, where template-assisted route is barely seen among the gas-phase reaction at elevated temperature. Here, we report nanowire (NW) templated chemical vapor deposition (CVD) synthesis of the few-layered MoS2 NTs by utilizing a sacrificial template in CVD process. The MoS2 NTs exhibit good crystallinity derived from high temperature gas-phase reaction. Moreover, the diameter of NTs and layer number of MoS2 are controllable. This work provides an effective technique route for the synthesis of the MoS2 NTs with only a few layers of thickness and would promote the synthesis of other one-dimensional (1-D) transition metal dichalcogenides (TMDs) nanomaterials.
