1、 Synthesis methods: Currently, the chemical methods for preparing molybdenum carbide mainly include high-temperature decomposition of compounds, programmed temperature reaction, high-temperature carbon reduction of molybdenum oxide, and gas-phase reaction of metal molybdenum compounds with certain volatility. The widely used method currently is temperature programmed reaction (TPRe), which uses a mixture of transition metal oxides, carbon sources, and hydrogen as raw materials. Through a process similar to temperature programmed reduction, the transition metal oxides undergo a reduction and carbonization (carburizing) reaction process at a set temperature. The commonly used carbon source materials include methane, ethane, ethylene, or carbon oxides (CO, CO2), etc., and the reaction temperature is generally controlled at 400-1000 ℃. Liang et al. synthesized nano molybdenum carbide using high surface area carbon materials as carbon sources and programmed temperature reduction method. 1. The program heating method uses ammonium molybdate to decompose at 500 ℃ to prepare MoO3. The alumina carrier is immersed in ammonium molybdate and ammonia solution, stirred for 0.5 hours, left at room temperature for 24 hours, evaporated in a water bath at 80-90 ℃, dried at 115 ℃ for 12 hours, and calcined at 500 ℃ for 4 hours to prepare a supported molybdenum trioxide precursor. Using the method of programmed heating, molybdenum carbide was prepared using n-hexane as the carbonization raw material. The process of programmed heating is as follows: raise the temperature from room temperature to 300 ℃, with a heating rate of 10 ℃/min; Raise the temperature from 300 ℃ to 600 ℃ at a rate of 1 ℃/min; Maintain a constant temperature of 600 ℃ for 2 hours. 2. Gas phase method generally uses high specific surface area activated carbon (with a specific surface area greater than 200m2/g) and transition metal volatile compounds, which are fed into a flowing reactor in a stoichiometric ratio, reacted at a high temperature of 900-1400 ℃ for a certain period of time, cooled in an inert gas, and recovered carbides. Heat a mixture of high surface area carbon and MoO3 in argon gas to 800 ℃, causing MoO3 to sublime and adsorb onto the carbon, and then raise the temperature to 1300 ℃ for a certain period of time to produce Mo2C There are reports that a hexagonal Mo2C can be obtained by reacting MoO3 with 1150m2/g carbon in a C/Mo molar ratio of 6:1, with a specific surface area of up to 213m2/g. Leclercq et al. evaporated volatile metal compounds into containers containing low-pressure hydrocarbons and directly carbonized them into carbides at high temperatures. By changing the gas composition and the type of metal compound precursor in the reactor, different carbides and carbon oxides can be produced. Nagai et al. used this method to prepare Mo2C/Al2O3 catalysts with three times higher activity than the impregnation method under vacuum conditions at 973K. But the disadvantage of this method is that the conditions are not easy to control and the synthesis amount is small. 3. Thermal decomposition method refers to the process of reacting transition metal oxides or halides with specified organic compounds to form metal organic compounds, which are then subjected to thermal decomposition reaction in an inert atmosphere. Bayer Corporation uses it to react with organic compounds containing two hydroxyl groups, remove excess organic compounds, and decompose them into metal carbides under vacuum or inert gas. Sehwartzkopf et al. directly carbonized metal oxide powders at high temperatures, but the resulting samples had a lower specific surface area. At present, the preparation of molybdenum carbide is developing towards practical applications with high specific surface area and high dispersibility. 4. Liquid phase reaction method Low temperature liquid phase reaction method refers to dissolving a series of substances in a suitable solvent, allowing them to undergo chemical reactions under relatively mild conditions. 
2、 Application areas: 
1. Cutting tools: Molybdenum carbide has extremely high hardness and wear resistance, so it is widely used in the manufacture of high hardness cutting tools, such as drill bits, milling cutters, turning tools, etc. 
2. Electronic materials: Molybdenum carbide has low electrical resistivity, good thermal stability, and a small coefficient of thermal expansion, making it suitable for use as a semiconductor material and energy storage material. Molybdenum carbide has good conductivity and high temperature stability, so it is widely used in the manufacture of electronic materials such as electrodes, capacitors, etc. 
3. Aerospace: Molybdenum carbide has good corrosion resistance and high temperature stability, so it is widely used in the aerospace field, such as manufacturing engine components, combustion chambers, etc. 
4. Molybdenum carbide can also be used as a coating material, which can effectively improve surface hardness and corrosion resistance, and is used to manufacture special coatings such as acid and alkali resistance and corrosion resistance. 
5. Catalytic performance of molybdenum carbide: It has been found that molybdenum carbide has high initial catalytic activity in the benzene hydrogenation reaction. Although the catalyst gradually becomes deactivated as the reaction progresses, its steady-state conversion frequency (TOF) can still be compared to precious metals Pt or Ru. Under normal pressure and 300 ℃ reaction conditions, the catalytic activity of α - MoC-x for thiophene hydrogenation desulfurization reaction is similar to that of commonly used hydrogenation desulfurization catalyst molybdenum sulfide. The main types of catalytic reactions catalyzed by molybdenum carbide catalyst are: (1) hydrogenation hydrolysis reaction; (2) HDS hydrogenation desulfurization and HDN hydrogenation denitrification reactions; (3) Isomerization reaction; (4) Hydrocarbon conversion and synthesis reactions; (5) Application in ammonia synthesis. 
3、 Storage method: 
This product should be sealed and stored in a dry and cool environment, and should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and use effectiveness. In addition, it should be avoided from heavy pressure, and should not come into contact with oxidants. It should be transported as ordinary goods.
