无机类富勒烯纳米粒子具有良好的润滑性能. 宏量制备高纯度的样品以满足性能测试的要求, 是目前面临的主要技术难题. 本文采用剥离-掺杂-水热处理这一工艺流程制备了多元金
属二硫化物纳米粒子, 应用XRD、TEM、HRTEM和EDS等分析手段对其形貌、晶相组成、结构和化学组成进行了表征. 实验结果表明, 多元金属二硫化物纳米颗粒具有管状形貌,管壁为
多层状结构, 化学组成为Ni_X(W_YMo_1-Y)_1-XS₂, 同时, 样品中具有类富勒烯结构的纳米粒子大幅度提高; 并依据实验结果对多元金属二硫化物纳米管的形成机理进行了探讨.

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.
