WS2 solid lubricant is a kind of sulfide solid lubricant, and is also one of the currently preferred solid lubricants, which has the advantages of low friction coefficient, strong adhesion, and good film-forming properties. In recent years, the ultra-low friction and ultra-low wear shown by hollow inorganic fullerene-like nano WS2 have attracted much attention.

How to prepare tungsten disulfide nanosheet? It is reported that tungsten disulfide (WS2) nanosheet powder can be prepared by mechanical peeling.

Nano tungsten disulfide, or nano WS2, is a very important additive in the production of high-performance lubricating oil. According to the experts, under the same conditions, the lubricating performance of the base oil added with WS2 nanoparticles is significantly better than the base oil added with conventional WS2 particles, and it has good dispersion stability. In addition, the lubrication performance of nano WS2 is superior to that of nano MoS2.

Tungsten disulfide nanosheet, or WS2 nanosheet, has good catalytic performance and visible light response performance, and also has good chemical stability, high corrosion resistance and excellent anti-toxicity, so that it is applied for fabricating catalytic anode of a low-temperature fuel cell.
