Production process: 

A new method for preparing crystalline transition metal boride CoB by solid-state reaction between cobalt oxide or hydroxide and borohydride. The method of the present invention: Mix cobalt oxide or hydroxide with borohydride in a molar ratio of 1:1-1:1.5, press it under pressure of 15-20MPa, keep it under argon protection at 400-800 degrees for 6-24h, and then slowly cool it to room temperature; The obtained product was thoroughly washed with deionized water and ethanol, and vacuum dried to obtain the product CoB. 

2. Mix the elements boron and cobalt in proportion, press and shape them, and heat them in a heating furnace to produce. 

Purpose: 

1. Amorphous Co-B is a new type of material with short-range ordered and long-range disordered structures, which belongs to the metastable state thermodynamically. At present, Co-B powder has been widely used as a catalyst for hydrogenation reactions and on-site hydrogen production reactions due to its excellent catalytic activity, hydrogenation activity, and hydrogenolysis activity. 

2. The use of cobalt boride modified bismuth vanadate film photoanode for photoelectrochemical water splitting Compared with a single BiVO film, the photocurrent of the cobalt boride modified bismuth vanadate film photoelectrode increased by 23 times 

3. Cobalt boride (Co2B) can be used as a catalyst for the generation of hydrogen from sodium borohydride in proton exchange membrane fuel cells. 

4. Tool material: Cobalt boride has extremely high hardness and good wear resistance, so it is widely used in the tool manufacturing industry. Tools made of cobalt boride have a long service life and excellent cutting performance. 

5. Electronic materials: Cobalt boride can also be an important component of electronic materials. Due to its high melting point and good thermal stability, cobalt boride can be used to prepare high-temperature electronic components. 

6. Magnetic materials: Cobalt boride is also widely used in the field of magnetic materials. Cobalt boride can be used to prepare high-performance magnetic materials such as magnetic recording media and permanent magnet materials. 

Packaging and storage: 

This product is packaged with inert gas and anti-static properties. It should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture and aggregation, which may affect its dispersibility and effectiveness.
