Molybdenum disulfide (MoS₂) is one of the well-known two-dimensional (2D) materials. Because of the tube shape, MoS₂ nanotube (NT) is expected to be used for high-performance application in semiconductor and catalyst, etc. Chemical Vapor Deposition (CVD) is a concise and efficient way to synthesize MoS₂ NT. Our laboratory has succeeded to synthesize MoS₂ NT using CVD with FeO nanoparticle as a catalyst.
In this study, we tried to explore an easier way to synthesize MoS₂ NT by CVD with turbulent flow. Synthesized MoS₂ NT is a zig zag type and we can confirm the hollow structure in the nanotube by cross sectional TEM image. In this method, we do not need catalysts and separation of MoS₂ NT from the catalyst.
