Abstract: The lubricating property of inorganic fullerene-like nanoparticles is excellent. As restricted by fabrication technology, only a few particles with fullerene-like structure in the micro-scale resultant can be
fabricated by updated approaches. And this can not meet the need for the test and evaluation of the capability of fullerene-like nanoparticles. In order to overcome this problem, a new approach of
exfoliation-adulteration-hydrothermal synthesis was used to fabricate multi-metal disulfide nanoparticles in macro-scale. The morphology, crystal phase, structure and chemical components of the resultants
were characterized by XRD, TEM, HRTEM and EDS respectively. These results show that multi-metal disulfide nanotubes can be fabricated by this new approach; The characteristic of the nanotubes is
multilayer, and they are composed of Ni, W, Mo and S elements. The percentage of the nanoparticle with fullerene-like structure in the sample is increased. We regard that the approach of
exfoliation-adulteration-hydrothermal synthesis is a promising technic for fabrication multi-metal disulfide nanoparticles with fullerene-like structure. On the basis of the above results, the formation mechanism of
Ni_X(W_YMo_1-Y)_1-XS₂ nanotube was discussed.
