The method of piece.
Background technique
Molybdenum nitride and tungsten nitride have very unique physics and a chemical characteristic, such as the hardness, excellent of high-melting-point, superelevation
Corrosion resistance, excellent conductivity it is magnetic, excellent heterogeneity and catalytic activity.Two-dimentional molybdenum nitride and tungsten nitride nanometer sheet,
Its thickness is less than 100nm, due to making it have higher ion diffusion speed with big electrochemistry and catalytic activation surface area
Rate, chemical property and catalytic activity.Therefore, in energy storage, electrode material, electrochemistry is urged for two-dimentional molybdenum nitride and tungsten nitride nanometer sheet
Change, hydrogenation catalyst, superconductor and electromagnetic interference shield etc. have important purposes.
But the method for the two-dimentional molybdenum nitride of preparation being currently known and tungsten nitride nanometer sheet is less, there is salt mould in document
Plate synthetic method, chemical liquid deposition and hydrothermal synthesis ammonia nitriding again, but these method higher costs, production efficiency
It is low, be not suitable for large-scale production.It the low cost of two-dimentional molybdenum nitride and tungsten nitride nanometer sheet, high efficiency and is prepared on a large scale and is still
A problem, this significantly limits it in the application of every field.
Summary of the invention
The purpose of the present invention solves the problems, such as that two-dimentional molybdenum nitride at present and the preparation of tungsten nitride nanometer sheet are difficult, provides a kind of new
Low cost, simple process, efficiently, be suitable for large-scale industrial production the two-dimentional molybdenum nitride of preparation or the side of tungsten nitride nanometer sheet
Method.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of method that low cost prepares two-dimentional molybdenum nitride or tungsten nitride nanometer sheet, it is characterised in that the following steps are included:
(1) molybdenum concentrate or tungsten disulfide and sodium carbonate are uniformly mixed by certain stoichiometric ratio, the ammonia in high temperature furnace
Nitridation reaction is carried out under atmosphere；
(2) product obtained in step (1) washed, filtered, being dried to obtain two-dimentional molybdenum nitride nanometer sheet or two dimension nitridation
Tungsten nanometer sheet.
Further, the charge ratio of molybdenum concentrate described in step (1) and sodium carbonate is the reality of molybdenum disulfide in molybdenum concentrate
Border content and sodium carbonate molar ratio 1:1.5-1:4；The charge ratio of the tungsten disulfide and sodium carbonate is molar ratio 1:1.5-1:
4；The nitridation reaction temperature is 600-900 DEG C；Washing methods described in step (2) is washing and pickling.
Further, the molybdenum concentrate can be replaced with molybdenum disulfide and molybdenum disulfide raw material as main component；Institute
The tungsten disulfide stated can use tungsten disulfide raw material substitution as main component；The sodium carbonate can use sodium hydroxide, carbon
Sour potassium, potassium hydroxide, lithium carbonate, lithium hydroxide, calcium carbonate, calcium oxide, calcium hydroxide, magnesium carbonate, magnesia or magnesium hydroxide
Instead of.
Compared with prior art, the present invention having the advantage that
1. the present invention uses molybdenum concentrate, tungsten disulfide and sodium carbonate for primary raw material, cost of material is low.
2. present invention process is simple, high production efficiency, production cost is low, is suitble to industrialization large-scale production two dimension molybdenum nitride
With tungsten nitride nanometer sheet.
3. two-dimentional molybdenum nitride and tungsten nitride nanometer sheet that present invention process is prepared, purity is high, thickness are thin.
