Abstract

The invention relates to a preparation method of high purity phase spherical molybdenum disulfide. The method comprises the following steps: ammonium heptamolybdate, thioacetamide, and a surfactant are dissolved in a solvent with uniformly mixing; a reducing agent is added, the prepared solution is transferred into a high pressure reaction vessel, the high pressure reaction vessel is sealed, the sealed high pressure reaction vessel is placed into a thermotank at 120-250 DEG C for 3-72 hours; temperature is cooled to room temperature, after filtering, washing and drying processes, spherical nanometer molybdenum disulfide is obtained. The prepared high purity phase nanometer molybdenum disulfide has the advantages of structured morphology, uniform and adjustable size, high sphericility, good dispersibility, simple synthesis process, mild condition, low cost, and simple synthesizer. The high purity phase nanometer molybdenum disulfide has wide applications to electrode materials, lubrication materials and catalysis fields, and is hopeful to be used in industrial production.

Description

technical field

[0001] The present invention relates to inorganic nano material molybdenum disulfide (MoS 2 ) preparation field, especially a preparation method of spherical nanomolybdenum disulfide. Background technique

[0002] Molybdenum disulfide has good optical, electrical, lubricating, catalytic and other properties, so it has good application potential in electronic detection, solid lubrication, heterogeneous catalysis, gas storage materials and petrochemical industries. Molybdenum disulfide has a typical layered structure, and the layers are combined by weak van der Waals force, which is easy to peel off, and ions are easily inserted between the layers. Each molybdenum atom in the monoatomic layer is surrounded by six sulfur atoms, in the shape of a triangular prism, exposing many Mo-S facets, which can be used as catalytic active centers. Nano-sized molybdenum disulfide has the advantages of quantum size effect, surface effect, and more exposed active centers, wh...
