How Is Ammonium Metatungstate Used in the Preparation of Tungsten Diselenide Nanosheets?

Ammonium metatungstate can be used as a precursor for the preparation of tungsten diselenide nanosheets. The synthesis involves the reaction of ammonium metatungstate with selenium powder in a high-temperature furnace, which results in the formation of tungsten diselenide nanosheets.
