The invention provides a method for preparing molybdenum disulfide nanosheets by ultrasonic-assisted chemical intercalation and belongs to the field of preparation of molybdenum disulfide nanosheets. The method provided by the invention comprises the following steps: performing ultrasonic reaction on molybdenum disulfide powder and n-butyl lithium under the protection of high-purity argon gas to obtain lithium-intercalated molybdenum disulfide; and adding ultra-pure water into a reactant, performing chemical stripping on a molybdenum disulfide bulk material to obtain single-layer molybdenum disulfide nanosheets, adding anhydrous ethanol for washing, and performing ultra-pure water dispersion and high-speed centrifugal separation so as to obtain a single-layer molybdenum disulfide nanosheet material which can be dispersed in water. Compared with the traditional method for preparing the molybdenum disulfide nanosheets by chemical intercalation, the method for preparing the molybdenum disulfide nanosheets, provided by the invention, has the characteristics of high reaction speed, high reaction yield, good stripping effect, simple operation, mild reaction conditions and easiness in large-scale production.
