Abstract

The invention discloses a molybdenum disulfide nanometer powder material with an aluminum sulfide housing and a preparation method of the molybdenum disulfide nanometer powder material, belonging to the technical field of preparation of nanometer materials. The nanometer powder material is of a core-shell structure, an MoS2 nanometer particle is used as an inner core, an Al2S3 layer is used as a housing; the particle size of the MoS2 inner core is 10nm-100nm, the Al2S3 housing layer is an amorphous Al2S3 layer and has a thickness of 1nm-10nm. According to the molybdenum disulfide nanometer powder material, by adopting a plasma arc discharge method, molybdenum powder and aluminum powder are briquetted into a block body according to a certain atomic percent to be used as an anode material, graphite is used as a cathode material, argon and hydrogen sulfide gases are introduced to be used as working gases, a certain distance is kept between a cathode and an anode, and arc discharge is achieved between the cathode and the anode, so that the MoS2 nanometer powder material with the Al2S3 housing is obtained. The preparation method is simple in preparation process, free from posttreatment procedure and low in cost; industrialized production is easily realized.

Description

technical field [0001] The invention belongs to the technical field of preparation of nanomaterials, in particular to a 2 S 3 ) Molybdenum disulfide (MOS 2 ) Nano powder material and preparation method thereof. Background technique [0002] Metal sulfides are a very important class of semiconductor materials. The broad application prospects of metal sulfide nanomaterials in photocatalytic materials, luminescent materials, nonlinear optical materials and photosensitive sensor materials have aroused strong research interest. Sulfide semiconductors play an increasingly important role in our production and life. As a MoS with unique properties 2 , also attracts special attention, because when the temperature exceeds its critical temperature, MoS 2 There will be a change in magnetic and conductive properties. It has a wide range of applications in solar cells, hydrodesulfurization catalytic reactions, as well as photoconductive materials and cathode materials for lithium-s...
