Nanotubes of the Disulfides of Groups 4 and 5 Metals
Nanotubes of HfS 2, ZrS 2, NbS 2, and TaS 2 have been obtained by the reduction of the corresponding metal trisulfides in a stream of H 2 (mixed with an inert gas in some cases) at elevated temperatures. The nanotubes have been characterized by transmission electron microscopy (TEM) and other techniques. These disulfide nanotubes make an important addition to the growing family of nanotubes of inorganic layered materials.
