What Are the Preparation Methods of Tungsten Disulfide Nanosheet? 56

Tungsten disulfide nanosheet (WS? nanosheet) is a typical transition metal tungsten compound. There are many different preparation methods, each of which has its own unique principles, operation procedures, advantages and disadvantages. Mechanical exfoliation Mechanical exfoliation is a classic two-dimensional material preparation technology that separates a single-layer or few-layer WS? nanosheet from bulk materials by physical means. This method uses tape to repeatedly stick bulk WS? crystals, or uses a special mechanical device to apply external force to overcome the weak…
