VS₂ Nanotubes Containing Organic‐Amine Templates from the NT‐VOx Precursors and Reversible Copper Intercalation in NT‐VS₂

Softly, softly: VS2 nanotubes (see electron micrograph, layer separation 1.6 nm) are prepared from vanadium oxide nanotubes by a “chimie douce” process. The VS2 nanotubes are remarkably stable; the corresponding bulk compound is unstable unless it is intercalated with alkali-metal atoms. The nanotubes reversibly intercalate copper with high capacity and thus could serve as precursors for conductors or contacts in electronic circuitry.
