Technical field
The present invention relates to a kind of method that solid state reaction prepares molybdenum disulfide nano sheet, belong to field of nano material preparation.
Background technology
MoS
2(molybdenumdisulphide) is a kind of diamagnetism and has the stratiform two-dimensional material of semiconductor property, and its crystalline structure has 1T, 2H and 3R three kinds, 1T-MoS
2with 3R-MoS
2configuration is metastable structure, usual 2H-MoS
2it is structural stability.2H-MoS
2in each molybdenum atom be that triangular prism column encloses by six sulphur atoms be that Mo-S faceted pebble is quite a lot of, specific surface area is large, and surfactivity is high, and frictional coefficient is low, is excellent catalyzer and solid lubricant, is widely used in catalytic material and lubricant.In recent years, researchist finds that molybdenum disulfide nano material has stronger lubrication and catalytic effect.In addition, because the size of nanometer materials is less, its separation surface is in neither the height state of disarray of long-range order, again non-short range order, this just makes to which create surface effects, small-size effect, quantum effect and macro quanta tunnel effect that bulk material does not have, show that it has the physical propertiess such as the light different with conventional material, heat, electricity, magnetic, thus arouse great concern.
Performance and its pattern, the structure of material have much relations, and by studying the relation of performance and pattern, we can further from going to inquire into various reaction mechanism, and the molybdenumdisulphide therefore preparing different-shape has very important effect.Wherein, two-dimension nano materials receives the concern of more and more people because of its various special property.
The preparation of molybdenum disulfide nano sheet and performance study are large focal spots in current nanotechnology research field.At present, the method preparing molybdenum disulfide nano sheet mainly comprises the technology such as hydro-thermal or solvent-thermal method, microemulsion method, coprecipitation method.Solid-state chemical reaction method method does not use solvent, has highly selective, high yield, simple technological process and other advantages, has become a kind of important method of nano materials.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of molybdenum disulfide nano sheet, utilize solid state reaction technique to prepare molybdenum disulfide nano sheet by regulating molybdenum salts, the synthesis for molybdenum disulfide nano sheet provides the simpler preparation method of one.
The invention discloses a kind of method that solid phase prepares molybdenum disulfide nano sheet.The present invention be using molybdenum salts and thioacetamide as reactant, at room temperature to be reacted by grinding, and then the molybdenum disulfide nano sheet of obtained two dimension.
The present invention uses process for solid phase synthesis to achieve the synthesis of molybdenum disulfide nano sheet, simple to operate, with low cost, environmental friendliness, and the preparation for molybdenum disulfide nano sheet provides a kind of new thinking.
