How to prepare tungsten disulfide nanorod? The prior processes usually require preparing a precursor first. The process is relatively complicated. And the obtained WS2 nanorods have non-uniform particle size and poor controllable morphology, which affect their application in tribology, photochemistry and other fields. In this regard, the researchers proposed a new preparation method of tungsten disulfide nanorods.

Preparing Tungsten Disulfide Nanorods by Hydrothermal Method
Dissolve 0.30 g of PEG600 into 70 mL of distilled water, and then add 1.40 g of CS(NH2) 2, 0.725 g of NH2OH·HCl and 1.56 g of (NH4)2WO40. After dissolving completely, adjust the pH value to about 6 with 2 mol/L HCl. After stirring for 30 min, the mixed solution was transferred to a 100 mL stainless steel reaction kettle, placed in a vacuum oven at 180 °C for 24 h, and cooled to room temperature. After centrifugation, the reaction product was washed repeatedly with deionized water and absolute ethanol, and finally dried under vacuum at 80 °C for 10 h to obtain a gray-black powder - tungsten disulfide nanorods.
