Nanotubes of Group 4 Metal Disulfides
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.
