Preparation method of flower-shaped molybdenum disulfide microspheres

The invention discloses a preparation method of flower-shaped molybdenum disulfide microspheres. The preparation method comprises the steps of dissolving ammonium molybdate tetrahydrate in deionized water to prepare a solution of 0.02-0.05 mol/L; adding thiourea to the solution, and stirring the mixture for 20-30 min by using a magnetic stirrer so that the solution is mixed uniformly, wherein the mol ratio of ammonium molybdate tetrahydrate to thiourea is (1 : 20) to (1 : 30); transferring the solution to a hydrothermal reaction kettle, performing hydrothermal reaction for 4-8 hours at 220-240 DEG, naturally cooling, centrifuging, washing by deionized water and ethyl alcohol, and drying again to obtain molybdenum disulfide microspheres. The preparation method of the flower-shaped molybdenum disulfide microspheres has the advantages that the cost is low, the process is simple and is easy to control, the appearances of the prepared microspheres are even, and the product output is high; the preparation method is applied to large-scale industrial production.
