Nickel boride is the common name of materials composed chiefly of the elements nickel and boron that are widely used as catalysts in organic chemistry. [ 1 ] [ 2 ] Their approximate chemical composition is Ni 2.5 B, [ 3 ] and they are often incorrectly denoted " Ni
Dinickel boride 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 2 NaBH 4 ↔ 2NaH + B 2 H 6 2Ni + 2 B 2 H 6 + NaH ↔ Ni 2 B + 3 BH 3 + 2 H 2 + Na
Trinickel boride can be obtained, as grains embedded in a nickel matrix, by heating Brown's P-1 and P-2 "nickel boride"catalyst to 250 °C. This catalyst is produced by reduction of nickel salts with sodium borohydride. [5] Trinickel boride can be obtained also by compressing nickel and boron powders with explosives. [6]
