Description
Technical field
The present invention relates to the preparing technical field of nano material, particularly lubriation material technical field.
Background technology
Transition-metal dichalcogenide, especially molybdenum disulfide have laminar structured, the model of interlayer similar to graphite
De Huali is very weak, easily peelable between layers, therefore its coefficient of friction is very low, easily slides；Covalent bond in layer is very
By force, illustrate that it has good mechanical strength, has good heat endurance in inert environments and freely hanged with surface
The features such as key, it can prevent from being pierced in metal surface protruding parts lubricating film, and can be right exposed to the sulphur atom of plane of crystal
Metal surface produces very strong adhesion, forms very firm film so that its greasy property is superior to graphite.
Compared with common molybdenum disulfide, MoS2Nanometer sheet is because of great specific surface area, table the features such as stronger adsorption capacity
Reveal more excellent greasy property.MoS2Nanometer sheet is used as lubriation material can significantly reduce its coefficient of friction and carry
High-wearing feature, has good application prospect in tribology.Vattikuti et al. successfully synthesizes MoS2Nanometer sheet, it is made
Excellent wear-resistant and reduction frictional behaviour is shown for lubricating additive, is seen《Use solvent structure MoS2Nanosphere and
The structural characterization of nanometer sheet》（Material science journal, 2015,50:5024-5038.）.
MoS2Nanometer sheet can be by mechanically pulling off method, electrochemical stripping method, embedding lithium stripping method, hydro-thermal method, solvent-thermal method,
Hummer methods, CVD, ultrasonic water bath method, hydrodynamic, ball-milling method, steam blow etc..But the above method can not
Meet that step is simple simultaneously, the nanometer sheet number of plies is controllable and requirement of large-scale production.
The content of the invention
It is simple, controllable with good friction performance, the nanometer sheet number of plies based on method it is an object of the invention to provide one kind,
And beneficial to the two-dimensional nanostructure MoS of industrialized production2The preparation method of nanometer sheet.
The present invention comprises the following steps：
1）Under magnetic stirring, molybdenum source and sulphur source are dissolved in deionized water, obtain the mixed solution of molybdenum source and sulphur source；
2）By 60~100 DEG C of dry powdery halloysite nanotubes（HNTs）After being mixed with the mixed solution of above-mentioned molybdenum source and sulphur source
Reacted；
3）Reaction is cooled to room temperature after terminating, and successively removes galapectite nanometer using hydrofluoric acid aqueous solution and aqueous hydrochloric acid solution washing
Pipe（HNTs）, obtain MoS2Crude product；
4）Using deionized water, absolute ethyl alcohol washing MoS2After crude product, centrifuging and taking obtains solid phase, through drying, grinding, obtains two wieners
Rice structure MoS2Nanometer sheet.
The present invention is with powdery halloysite nanotubes（HNTs）For template, by step 2）, the mixed solution of molybdenum source and sulphur source
Middle molybdenum source is deposited with sulphur source in template outer surface and interlayer, and molybdenum source can be reacted rapidly with sulphur source, and molybdenum disulfide is produced in a template
Nucleus, the nucleus of generation quickly grows into curling sheet；By step 3）Removing template is removed, curly molybdenum disulfide is obtained and slightly produces
Product；By step 3）After processing, curly molybdenum disulfide own tension expansion forms the two-dimensional nanostructure of multilayer chip
MoS2Nanometer sheet.
The step 2）In, halloysite nanotubes during for mixing（HNTs）Temperature be 60~100 DEG C.HNTs
Enough solution can be absorbed after removing intermediary water, interlayer template action is made full use of.
The present invention is with halloysite nanotubes（HNTs）It is carrier by controlling solid-liquid volume ratio, utilizes pipe outer wall template and layer
Between the method for intercalation template prepare two-dimensional nanostructure MoS2Nanometer sheet, compared with prior art, technical advantage body of the invention
Now：
1st, the template that the present invention is used is natural halloysite nanotubes, and cost is low, and stability is good.
2nd, the present invention prepares nanometer sheet using template to have taken into account step simultaneously simple, and the nanometer sheet number of plies is controllable and scale
The advantage of metaplasia production.
Further, step 1 of the present invention）In, the molybdenum source is ammonium molybdate or sodium molybdate.Ammonium molybdate and sodium molybdate are all
It for the principle that is easy to get, can decompose in a heated condition, produce MoS2。
The step 1）In, the sulphur source is thiocarbamide or thioacetamide or vulcanized sodium.In a heated condition, these sulphur sources
H is produced with water reaction2S, produced hydrogen sulfide is very strong reducing agent, can be by Mo+6It is reduced to Mo+4.In addition, hydrogen sulfide is also
Vulcanizing agent is served as, sulphur source is provided for generation molybdenum disulfide.
The step 1）In, in the mixed solution of the molybdenum source and sulphur source the mol ratio of molybdenum atom and sulphur atom be 1: 2~
4.The consumption of each material is easy to control solid-liquid volume ratio more than, and such as sulphur source is very few, then MoS2Easily it is oxidized；Such as sulphur source mistake
It is many, then waste raw material.
The step 1）In, the temperature conditionss of the dissolving are 30~60 DEG C.The special meaning dissolved using the temperature
Justice：Do not reacted between dissolution of raw material, two kinds of raw materials.
The step 2）In, the powdery halloysite nanotubes（HNTs）For 1-dimention nano tubular structure, length is 200~
500 nm, a diameter of 50~100nm, interlayer structure are 7~10.Use what the material of tool above characteristic was had by carrier
Special Significance：With larger external surface area, surface active groups are more, molybdenum disulfide can using outside surface area as template,
Prepare the more MoS of the number of plies2Nanometer sheet, and nanometer interlayer structure is 7~10, can be as template contral MoS2Nanometer
The number of plies of piece, the number of plies that nanometer sheet is made is 2~3 layers.
The step 2）In, the halloysite nanotubes and the mixing ratio of molybdenum source and sulphur source are 100 mL: 3.8~215 g:
3.2~330 g.The Special Significance being had using the amount ratio：
1st, solid-liquid volume ratio is 1:When 40, molybdenum source, sulphur source are mainly in template outside deposition；
2nd, solid-liquid volume ratio is 1：When 0.2, molybdenum source, sulphur source are first filled with HNTs interlayers；
3rd, solid-liquid volume ratio therebetween when, either way occur；
4th, the controllable purpose of the nanometer sheet number of plies has been reached, the number of plies that can control to prepare nanometer sheet is 2~8 layers.
The step 2）In, the reaction the temperature of mixed system be 180~240 DEG C, the conditions of 5~15 rpm rotating speeds
It is lower to carry out.The Special Significance being had using above reaction condition for present invention process：
1st, rotating speed is slower, causes HNTs powder to deposit, it is impossible to preferably to play template action；
2nd, under cryogenic, the crystallinity of the molybdenum disulfide of synthesis is poor；
3rd, with the rise of temperature, the crystallinity of the nanometer sheet of synthesis is preferable；
4th, the crystallinity of nanometer sheet, which has reached, further rises high temperature increases rotating speed after requirement, cause the waste of the energy；
The step 3）In, HF mass percent is HCl in 20~40%, aqueous hydrochloric acid solution in the hydrofluoric acid aqueous solution
Mass percent is 20~38%.The Special Significance that the concentration of each material has more than：
1st, because template HNTs is mainly by alumino-silicate, so template can be removed from hydrofluoric acid and hydrochloric acid；
2nd, the concentration of acid solution is too low, and template can not be removed thoroughly totally；
3rd, it is easy to purchase, convenient reduction production cost.
