Nickel boride is an
efficient catalyst and reducing agent. It is used as a heterogeneous
hydrogenation catalyst. It can also be used to cleave thioacetals. In 1963, H.
C. Brown and Charles A. Brown reported the synthesis and performance of two
similar catalysts, which they denoted by “P-1” (the same as Paul’s)
and “P-2”, obtained by reacting sodium borohydride with nickel
acetate in water and ethanol, respectively. Nickel borides are inorganic
compounds with the chemical formula NixBy, where x and y vary. A common formula
is Ni2B, which is available in two forms, known as P−1 and P−2. Nickel boride
is an ionic compound with a hexagonal crystal structure. “Ni. 2B”.
The boride layer, produced on Nickel 201-alloy, was characterized by the lowest
average hardness of 17.97 ± 1.59 GPa and Young’s modulus of 217.89 ± 20.72 GPa.
Among various metal borides, nickel boride, Ni2B, is regarded as a potential
industrial catalyst for hydrogenation reactions. Previous investigations
indicated that nickel boride nanoparticle is useful in catalysts for the fuel
cell’s electrodes. It is a type of electroless nickel plating. Similarly, the
molecules of alkyne are adsorbed by the surface of Ni2B. Slowly stepwise, the
adsorbed hydrogen and the alkyne form a bond, and syn-addition occurs before
the organic molecule leaves the catalyst surface. Nickel Boron is an advanced
metal finish that offers high resistance to wear and corrosion and has an
ultra-low friction coefficient. Black nickel has a black tint on a nickel
finish. A polished nickel finish is mirror-like but has a silvery tint; black
nickel makes it darker. It is a black, mirror-like finish and can go well with
black TVs, kettles, and toasters. If
