Catalysis in industry - The Essential Chemical Industry

The most common examples of heterogeneous catalysis in industry involve the reactions of gases being passed over the surface of a solid, often a metal, a metal oxide or a zeolite .... When iron is used as the catalyst in the Haber Process, aluminium oxide is added and acts as a barrier to the fusion of the metal particles.

Catalysis - Wikipedia

Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst (/ˈkætəlɪst/), which is not consumed in the catalyzed reaction and can continue to act repeatedly. Often only tiny amounts of catalyst are required in principle. In general, the reactions occur faster...
