英文摘要	Single-and double-walled WS2 nanotubes of small diameter (<10 nm) and few layers (<4) have been synthesized by heating ultrathin W18O49 nanowires and S powders in an H-2/Ar atmosphere at 840 degrees C. In the process of formation and growth of a WS2 nanotube, the W18O49 phase transformed first into an amorphous WS3 structure via the absorption and diffusion of the sulfur atoms to substitute the oxygen atoms, and followed by a phase transition from amorphous WS3 to 2H-WS2 by losing sulfur atoms to form the shell of the WS2 nanotube. [GRAPHICS] IMPACT STATEMENT Synthesis of thin WS2 nanotubes with single- and doubled-walled structure from ultrathin W18O49 nanowires is developed and their structure and growth are studied using electron diffraction and microscopy.
