Raney nickel /ˈrn ˈnɪkəl/, also called spongy nickel, is a fine-grained solid composed mostly of nickel derived from a nickel-aluminium alloy. A variety of grades are known, but most are gray solids. Some are pyrophoric, most are used as air-stable slurries. Raney nickel is used as a reagent and as a catalyst in organic chemistry. It was developed in 1926 by American engineer Murray Raney for the hydrogenation of vegetable oils.
