Rhenium(IV) Sulfide Nanotubes

Abstract
Rhenium(IV) sulfide, ReS2, has been prepared with nanotubular morphology by carbon nanotube templating. A multiwall carbon nanotube material was impregnated with solutions of NH4ReO4 or ReCl5, followed by drying and sulfidation with H2S at 1000 °C. The composite material synthesized was characterized by high-resolution transmission electron microscopy and X-ray powder diffraction. Like previously described MS2 nanotube compounds, ReS2 has a layered structure consisting of S−M−S layers. Re atoms in ordinary ReS2 are octahedrally coordinated with S, and tetranuclear metal clusters are present as a consequence of metal−metal bonds.
