How to Prepare Oil-soluble Tungsten Disulfide Nanosheet? 293

How to prepare oil-soluble tungsten disulfide nanosheet? The researchers used tungsten hexachloride as the source of tungsten, and thioacetamide and thiourea as the active sulfur sources, and reacted at a constant temperature of 100-200 °C for 60 min in the presence of surface modifiers to obtain oil-soluble WS2 nanosheets. The obtained oil-soluble WS2 nanosheets have high purity, uniform size and two-dimensional sheet structure, and have broad application prospects in the fields of lubricant nano additives and the like.
