Description
Technical field
The invention belongs to metal molybdenum technical field, is related to molybdenum bisuphide, and in particular to a kind of monolayer or few layer molybdenum bisuphide
The preparation method of nano material.
Background technology
Class Graphene molybdenum bisuphide (the Graphene-like MoS being made up of monolayer or few layer molybdenum bisuphide2) it is a kind of
New Two Dimensional with similar graphene-structured and performance (2D) lamellar compound, in recent years with its unique physics, chemical
Matter and become emerging study hotspot.Monolayer or few layer molybdenum bisuphide are made up of the single or multiple lift molybdenum bisuphide of hexagonal crystal system
The two dimensional crystal material with " sandwich " layer structure, monolayer molybdenum bisuphide is made up of three layers of atomic layer, middle one
Layer is molybdenum atom layer, and upper and lower two-layer is sulphur atom layer, and molybdenum atom layer forms class " sandwich " folded by two-layer sulphur atom layer and ties
Structure, molybdenum atom form two-dimensional atomic crystal with Covalent bonding together with sulphur atom；Few layer molybdenum bisuphide is by some monolayer molybdenum bisuphide
Composition, is usually no more than five layers, and interlayer has weak Van der Waals force, and interlamellar spacing is about 0.65nm.
Used as the important two-dimensional layer nano material of a class, monolayer or less layer molybdenum bisuphide are with " the sandwich folder of its uniqueness
The heart " layer structure is widely used in various fields such as lubricant, catalysis, energy stores, composites.Compared to the zero of Graphene
There is regulatable band gap in band gap, class Graphene molybdenum bisuphide, possess brighter prospect in field of photoelectric devices；Compare
In the three-dimensional bulk structure of silicon materials, class Graphene molybdenum bisuphide has the two-dimensional layered structure of nanoscale, can be used to system
Manufacturing semiconductor or the electronic chip that specification is less, efficiency is higher, will obtain extensively in fields such as follow-on nano-electric devices
Using.
Monolayer or few layer molybdenum bisuphide are in the property of the aspect such as heat, electricity, light, mechanics and its in the latent of field of optoelectronic devices
The extensive concern of scientific research personnel is caused in application.However, general chemistry, Physical are difficult to prepare with layer structure
Monolayer or few layer molybdenum bisuphide, the method that can be adopted at present mainly have：Micromechanical forces stripping method, lithium ion graft process, liquid phase
The stripping method of ultrasonic method etc. " from top to bottom ", and the synthesis of high temperature thermal decomposition, vapour deposition, hydro-thermal method etc. " from bottom to top "
Method.
In the preparation method of " from top to bottom ", micromechanical forces stripping method operates relative ease with which and extent of exfoliation height is
The method of the maturation the most of application at present, it can obtain monolayer molybdenum bisuphide and peel off product have higher carrier mobility,
Typically it is used for making field-effect transistor, but it has preparative-scale little and repeatable poor shortcoming.
Lithium ion graft process is current charge stripping efficiency highest method, and it is applied widely, is used for secondary cell and sends out
Optical diode, Chinese patent for example Application No. 201310187544.9,201310561235.3,201410059743.6,
201410086208.X, by the use of n-BuLi etc. as intercalated molecule, by methods such as stirring, solvent thermal to platelike molybdenumdisulfide
Intercalation is carried out, the supersound process that is hydrolyzed afterwards obtains molybdenum disulfide nano sheet.However, needing during lithium ion graft process intercalation processing
Anaerobic water-less environment is wanted, requires harshness, and remove lithium ion easily to cause monolayer or few layer molybdenum bisuphide to industrial production environment
Aggregation.
Liquid chromatography ultrasound rule is latest development method out, it with simple to operate, preparation condition relative loose just by
It is widely used in opto-electronic device, the molybdenum bisuphide dispersion liquid elder generation that the Chinese patent of Application No. 201410081869.3 will be prepared
After carry out low high-power two step ultrasound, stripping prepares molybdenum disulfide nano sheet.But liquid chromatography ultrasound method needs large power supersonic
Equipment and long-time supersound process, limit industrialized production, and its extent of exfoliation and charge stripping efficiency is below first two method,
And in product monolayer molybdenum bisuphide content it is relatively low.
The Chinese patent of Application No. 201310704356.0 is disclosed to be carried out to molybdenum bisuphide using liquid nitrogen using one kind
Pre-treatment and then the method that ultrasound is peeled off to improve nanoscale twins charge stripping efficiency in NMP；Application No.
The Chinese patent of 201410086208.x disclose one kind by molybdenum bisuphide the intercalation processing under High Temperature High Pressure, then again by super
Sound realizes the method peeled off；The Chinese patent of Application No. 201110347902.9 discloses a kind of using jet flow cavitation technique reality
The now stripping to molybdenum disulfide nano sheet layer；The Chinese patent of Application No. 201410717991.5 discloses a kind of using oxidation
After agent oxidation, ultrasonic Separation obtains the strip preparation method of molybdenum disulfide nano sheet layer.Summarize these molybdenum disulfide nano sheet layers
Technology of preparing is peeled off, the problems such as preparation process cycle length, energy consumption are big, charge stripping efficiency is remained to be further improved is still suffered from.
In the synthetic method of " from bottom to top ", chemical vapour deposition technique application is more, such as Application No.
201410087035.3 Chinese patent is placed in molybdenum source and sulphur source in ceramic boat, and ceramic boat is placed in horizontal pipe furnace
Portion, after evacuation, under argon protection, high temperature prepares molybdenum disulfide nano sheet.However, chemical vapour deposition technique reaction temperature is high,
600 DEG C～850 DEG C, need inert gas shielding, product pollution environment damages health, it is tired to be that three-protection design brings
It is difficult.
In addition using hydro-thermal method Chinese patent for example Application No. 201210311761.X, 201310547151.4,
201410361617.6, molybdate is carried out into hydrothermal treatment consists in sulfur-containing compound solution, different-shape after cleaning-drying, is obtained
Molybdenum disulfide nano sheet.However, solvent-thermal method is related to the regulation and control to temperature, pressure, high to equipment requirements, reaction time is long,
It is unfavorable to use industrialized production.
" from bottom to top " synthetic method, it may be possible to which, due to the hyperpyrexia and chemical stability of molybdenum bisuphide material structure, which grinds
Study carefully, remain the problems such as preparation cost height, technology controlling and process complexity, and class graphite is obtained by synthetic method
The purity and light of alkene molybdenum bisuphide, electrical property etc. are still inferior to stripping method.
So, either prepared using the preparation method of synthetic method or existing " from top to bottom " " from bottom to top " at present single
Layer or few layer molybdenum bisuphide, have that yield is little or the low defect of charge stripping efficiency, how to improve monolayer or few layer molybdenum bisuphide
Preparation method remain current to realizing preparation process is simple, preparation efficiency high, favorable repeatability and mass production
Research emphasis.
