The Haber Process and Catalysis

The catalyst used in the Haber process is magnetite (FeO) fused with smaller amounts of promoters consisting of other metal oxides. The catalyst is ground finely such that it has a large surface area of aboutmg, and the magnetite is reduced to iron. The large surface area allows gaseous molecules to rapidly absorb and react.
