摘要

Abstract

BSTRACTSingle- and double-walled WS

nanotubes of small diameter (10 nm) and few layers (4) have been synthesized by heating ultrathin W

nanowires and S powders in an H

/Ar atmosphere at 840°C. In the process of formation and growth of a WS

nanotube

the W

phase transformed first into an amorphous WS

structure via the absorption and diffusion of the sulfur atoms to substitute the oxygen atoms

and followed by a phase transition from amorphous WS

to 2H-WS

by losing sulfur atoms to form the shell of the WS

nanotube.
