Template synthesis and characterization of molybdenum disulfide nanotubules
Molybdenum disulfide nanotubules were prepared by thermal decomposition of ammonium thiomolybdate ((NH(4))(2)MoS(4)) precursors on anodized aluminum oxide template. Large quantities of hollow MoS(2) nanotubules with the bamboo-like structure were obtained. The morphology and structures of MoS(2) tubules were characterized by scanning electron microscopy, high-resolution transmission electron microscopy, energy dispersive spectroscopy, electron diffraction and optical absorption spectroscopy. MoS(2) nanotubules completely reflected the three-dimensional structure of nanopores in template. The properties of Mo-S chemical bonds in lattice structure and the wetting state between porous surface and precursor have a great effect on the formation of sections in nanotubules, the ridges in the nanopores also play a very special role of this formation.
