Synthesis of WS2 nanostructures from the reaction of WO3 with CS2 and mechanical characterization of WS2 nanotube composites.

Abstract

Tungsten disulfide (WS(2)) nanometer sheets, spheres, fibers and tubes were generated by a synthetic pathway that avoids the use of H(2)S as the source of sulfur and employs instead CS(2) vapor, carried by an Ar or N(2)/H(2) stream in a heated tubular furnace, for the reaction with WO(3) precursor powders. The experiments were conducted at temperatures… (More)
