 Embodiment 1, preparation molybdenum disulfide nanoparticles
 Commercially available micron-sized molybdenum disulfide particles (2 microns in particle size) were mixed with 1-butyl-3-methylimidazolium hexafluorophosphate to obtain a mixture in which micron-sized molybdenum disulfide particles were mixed with 1 The mass ratio of -butyl-3-methylimidazolium hexafluorophosphate is 1:1; then the mixture is placed in a mortar for grinding, and the grinding time is controlled to be 10 hours; then the ground mixture is used The filter membrane with a pore size of 220nm is filtered and separated to obtain molybdenum disulfide nanoparticles.
 The transmission electron micrograph of the molybdenum disulfide nanoparticles prepared in this embodiment is as follows: figure 1 As shown in the scanning electron micrograph figure 2 It can be seen from the two figures that the particle size of the prepared molybdenum disulfide nanoparticles is 100-200nm.
 Embodiment 2, preparation molybdenum disulfide nanoparticles
Molybdenite, 1-butyl-3-methylimidazolium hexafluorophosphate and DMSO are mixed to obtain a mixture, in which molybdenite and 1-butyl-3-methylimidazolium hexafluorophosphate and The mass ratio of the DMSO mixture is 1:1000 (the mass ratio of 1-butyl-3-methylimidazolium hexafluorophosphate and DMSO is 4:1); then the mixture is placed in a mortar for Grinding, ultrasonic treatment after grinding, controlling the grinding time to 0.5 hours, and ultrasonic time to 3 hours; then the mixture after grinding and ultrasonic is centrifuged, and the remaining large molybdenum disulfide is removed by centrifugation at 4000rpm, and the above The supernatant was centrifuged at a rotational speed of 8000 rpm, and the precipitate at this rotational speed was collected to obtain molybdenum disulfide nanoparticles.
