Reney's nickel, differently "skeletal nickel" — the firm microcrystallic porous nickel catalyst used in many chemical and technology processes; the way of its preparation was offered in 1926 by the American engineer Murray Reney. Represents the gray high-disperse powder (particle size usually 400 — 800 nanometers) containing in addition to nickel, aluminum quantity (up to 15 masses. %) and saturated with hydrogen (to 33 at. %). Particles of powder have large number of time owing to what the specific surface makes about 100 m ²/g. Reney's nickel is pyrophorous, that is self-ignites on air at the room temperature therefore it is stored under sheet of water, alcohol or gasoline.

Reney's nickel is widely applied as the catalyst of various processes of hydrogenation or recovery by hydrogen of organic compounds (for example, hydrogenations of arenes, alkenes, vegetable oils, etc.). Accelerates as well some processes of oxidation by air oxygen. Structural and thermal stability of nickel of Reney allows to use it with the broad range of conditions of carrying out reaction; in laboratory practice its repeated use is possible. Nickel of Rhenium is catalystically much less active, than platinum group metals, but are much cheaper than the last.

Receive Reney's nickel alloyage at 1200 °C of nickel with aluminum (20-50% of Ni; sometimes insignificant amounts of zinc or chrome) are added to alloy then the ground alloy for removal of aluminum is processed hot solution of sodium hydroxide with concentration by 10 — 35%; the rest is washed out water in the atmosphere of hydrogen. The principle which is the cornerstone of preparation of nickel of Reney is used also for receiving catalystically active forms of other metals — cobalt, copper, iron etc.
