Not to be confused with Rieke nickel.
Raney nickel /ˈreɪniː ˈnɪkəl/, also called spongy nickel,[1] is a fine-grained solid composed mostly of nickel derived from a nickel–aluminium alloy.[2][3] Several grades are known, of which most are gray solids. Some are pyrophoric, but 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.[4][5] Raney is a registered trademark of W. R. Grace and Company. Other major producers are Evonik and Johnson Matthey.
