Description
Technical field
The present invention relates to a kind of method that solid phase method prepares molybdenumdisulphide-zinc sulfide heterojunction nano material, belong to field of nano material preparation.
Background technology
In recent years, the physics-chem characteristic of uniqueness that has due to itself of nano material and receive the extensive concern of researcher.Zinc sulphide, as a kind of very important semiconductor nano material, because it has the character such as special optical, electrical, thermal and magnetic, and shows huge application prospect in fields such as light emitting semiconductor device, nonlinear optical material, photochemical catalysis.But zinc sulfide nano-material, due to small-size effect and surface effects etc., makes it very easily reunite in preparation process, and then have influence on its performance and practical application.Therefore, people have employed multiple method to slow down the reunion of zinc sulfide nano-material.Wherein, template is adopted can effectively to stop it to reunite as carrier.Molybdenum disulfide nano sheet is owing to having large specific surface area and high chemical stability and causing the great interest of people.Zinc sulphide and molybdenum disulfide nano sheet compound as carrier, can be stoped the reunion of zinc sulfide nano-material by the specific surface area that molybdenum disulfide nano sheet is large for this reason effectively.
At present, the method preparing molybdenumdisulphide-zinc sulfide heterojunction nano material comprises hydrothermal method and microwave method etc., but these methods relate to experiment condition harshness, the high deficiency of energy consumption, thus exploitation is a kind of simply, high yield, eco-friendly synthetic method are still very urgent.Rare earth chemical method have simple to operate, cost is low, output is high and advantages of environment protection, has become a kind of effective ways of nano materials.
Summary of the invention
The object of the present invention is to provide the preparation method of a kind of molybdenumdisulphide-zinc sulfide heterojunction nano material, is utilize molybdenum disulfide nano sheet for template employing rare earth chemical reaction is to prepare molybdenumdisulphide-zinc sulfide heterojunction nano material.The method overcome zinc sulfide nano-material and serious agglomeration phenomenon occurs in preparation process, and achieve the compound of molybdenumdisulphide and zinc sulphide.
The invention discloses a kind of method that solid phase prepares molybdenumdisulphide-zinc sulfide heterojunction nano material.The present invention be using metal zinc salt, ammonium molybdate and thioacetamide as reactant, at room temperature to be reacted by grinding, and then obtained molybdenumdisulphide-zinc sulfide heterojunction nano material.
The present invention is using molybdenumdisulphide as template, process for solid phase synthesis is used to achieve the synthesis of molybdenumdisulphide-zinc sulfide heterojunction nano material, the method is simple to operate, do not use solvent, high yield, cost low, and the preparation for zinc sulfide-based matrix material provides a kind of new thinking.
