Abstract

The invention relates to a method for preparing MoS2 microspheres by a solvent hot method, which comprises the following preparation steps: 1) mixing molybdenum source compounds and sulfur source compounds into an alcohol solvent, sufficiently stirring the mixture, and carrying out ultrasonic processing for sufficiently dispersing the mixture; 2) then, transferring the uniformly dispersed mixture into a reaction kettle for carrying out constant-temperature reaction; and 3) carrying out natural cooling, separation, washing and drying on reacting substances to obtain black MoS2 microspheres. The invention has the advantages of mild reaction condition, good reaction reproduction quality, simple preparation process, low preparation cost and high product yield and purity, and is hopeful to realize mass production. The MoS2 products prepared by the solvent hot method of the invention have very important application prospects in all aspects of energy storage, catalysts, solid lubricating agents and the like.

Description

【Technical field】

[0001] The present invention relates to inorganic material MoS 2 The field of preparation, especially a method of preparing MoS by solvothermal method 2 microsphere method. 【Background technique】

[0002] Molybdenum disulfide (MoS 2 ) is a transition metal layered binary compound, which has diamagnetic and semiconducting properties, and also has good optical, electrical, lubricating, catalytic and other properties, and has always attracted people's attention. Molybdenum disulfide belongs to the hexagonal crystal system. There are quite a lot of Mo-S facets, and the specific surface area is large. There are strong covalent bonds in the layer, and weak van der Waals force between the layers. The layers are easy to peel off and have good properties. anisotropy with a lower friction factor, and due to the strong adhesion of S to metals, MoS 2 Can be well attached to the metal surface and always play a lubricating function, even under high temperature, high ...
