About Nickel Boride Ni2B Powder:
Nickel Boride is a chemical compound of nickel and boron with the formula Ni2B. It is one of the borides of nickel. The formula “Ni2B” and the name “nickel boride” are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride.
Nickel boride catalyst can reduce unsaturated ethers, alcohols, aldehydes, esters, amines and amides to their corresponding saturated compounds without hydrogenation reaction. Unsaturated nitriles can be reduced to primary amines, while epoxides remain unchanged. In addition to sodium borohydride, dimethoxyborane (Meo)2BH4 or lithium borohydride LiBH4 can react with nickel chloride to obtain nickel boride catalysts for such reactions. It is worth emphasizing that only NiCl2 showed catalytic activity in the combined catalytic reduction of 2-methyl quinoline by a variety of transition metal salts, such as CoCl2, NiCl2, CuCl2, CrCl3 and sodium borohydride.

How is Nickel Boride Ni2B Powder produced?
Nickel Boride Ni2B can be obtained (together with other nickel borides) by heating sodium borohydride with powdered nickel-metal up to 670 °C in a closed vessel so that the released hydrogen creates a pressure of up to 3.4 MPa. The main reactions can be summarized as
2NaBH4 ↔ 2NaH + B2H6
2Ni + 2B2H6 + NaH ↔ Ni2B + 3BH3 + 2H2 + Na
but other reactions occur, yielding other borides.
Application of Nickel Boride Ni2B Powder:
Nickel boride catalyst is prepared by the reaction of nickel chloride NiCl2 with boron hydrogen reagents such as sodium borohydride NaBH4. It can be used for selective hydrogenation reaction, desulfurization reaction, dehalogenation reaction, hydrolysis reaction, and reduction of nitro and other functional groups.
The nickel boride catalyst prepared by the reaction of NiCl2 and NaBH4 can also be used for desulfurization reaction. Compared with the Raney nickel catalyst used in the traditional desulfurization reaction, it can obtain a higher yield, and at the same time, it can avoid the disadvantages of Raney nickel such as strong alkalinity, flammability and sensitivity to air and moisture.
In addition, thioamides, sulfides and sulfides can all be desulfurized under the catalysis of nickel boride to obtain corresponding hydrocarbons
Primary, secondary, and tertiary aliphatic nitro compounds can be reduced to amines in the presence of nickel boride.
The NiCl2/NaBH4 combination also achieves dehalogenation and hydrolysis reactions, reducing many α-bromoketones to ketones, or dibromo ketones to olefines, and reducing benzyl, allyl, and propargyl esters to the corresponding alkanes.
Storage Condition of Nickel Boride Ni2B Powder:
The damp reunion will affect Ni2B powder dispersion performance and using effects, therefore, nickel boride Ni2B powder should be sealed in vacuum packing and stored in cool and dry room, the nickel boride Ni2B powder can not be exposure to air. In addition, the Ni2B powder should be avoided under stress.
