Tungsten Disulfide Nanosheet Applied for Fuel Cell

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.
