Tungsten disulfide nanosheet, or WS2 nanosheet, has a unique two-dimensional structure, and has advantages of excellent optical properties, high corrosion resistance, structural stability and anti-poisoning capabilities, so that it can act as a catalyst for anodization in a fuel cell. Tungsten disulfide nanosheets are used to replace the original precious metal platinum or platinum alloy. Pure platinum is easily poisoned by intermediate products such as carbon monoxide, and the catalytic performance and stability of pure platinum catalysts are relatively poor.

Some researchers prepared tungsten disulfide ultrafine powder by liquid phase precipitation method using sodium sulfide and sodium tungstate solution as raw materials. The obtained WS2 powder has good dispersion and uniform particle distribution.

What is tungsten disulfide? Tungsten disulfide is a new fine tungsten chemical product, with molecular formula of WS2, and gray-black appearance. WS2 is an important lubricant. WS2 can also be used as a petroleum catalyst.

High purity coarse tungsten disulfide powder refers to tungsten disulfide (WS2) powder with a purity greater than 99.9% and a larger particle size. The specifications of high-purity coarse tungsten disulfide can be WS2 powder with a Fischer particle size F.S.S.S of 1.9 μm and a laser particle size of 15-18 μm; Or WS2 powder with a Fischer particle size F.S.S.S of 3.8 μm and a laser particle size of 20-24 μm; Or a WS2 powder with a Fischer particle size F.S.S.S of 5.0 μm and a laser particle size of 25-28 μm, and so on.
