Commercially available Raney nickel has an average Ni surface area of 100 m2 per gram of catalyst.

Raney nickel is used as a reagent and as a catalyst in organic chemistry.

The surface area of Raney nickel (and related catalysts in general) tends to decrease with increasing leaching temperature.

A high catalytic activity, coupled with the fact that hydrogen is absorbed within the pores of the catalyst during activation, makes Raney nickel a useful catalyst for many hydrogenation reactions.

Industrial applications A practical example of the use of Raney nickel in industry is shown in the following reaction, where benzene is reduced to cyclohexane.

This resistance allows Raney nickel to be stored and reused for an extended period however, fresh preparations are usually preferred for laboratory use.

Safety Due to its large surface area and high volume of contained hydrogen gas, dry, activated Raney nickel is a pyrophoric material that should be handled under an inert atmosphere.

Additionally, the solubility of Raney nickel is negligible in most common laboratory solvents, with the exception of mineral acids such as hydrochloric acid, and its relatively high density (about 6.5 g cm3) also facilitates its separation from a liquid phase after a reaction is completed.
