Green Nickel Oxide as a Catalyst in Organic Reactions

Nickel monoxide is an inorganic substance with the chemical formula of NiO and is a greenish-black cubic crystal. Soluble in acid and ammonia, insoluble in water. The color turns yellow when heated. From the reaction of nickel with oxygen at temperatures above 400 ° C or from the pyrolysis of nickel carbonate at 350 ° C. It is used for making alloys, storage batteries, glass, enamel, ceramics, electronic components, nickel salts and catalysts.
