Abstract:
Thermal decomposition of the respective trisulfides in a reducing (H2/inert gas) atmosphere has enabled nanotubes of HfS2, ZrS2, and TiS2 to be synthesized and characterized. The dimensions of the nanotubes formed depend on the Group 4 metal used. The transmission electron micrograph image shows nanotubular structures of HfS2 with outer diameters of 55–60 nm and inner core diameters of 17–30 nm.
