Ammonia synthesis over multi‐promoted iron

The feasibility of producing ammonia synthesis catalysts from high‐energy ball‐milling of a simple mixture of the constituent oxides has been investigated. The effect of ball‐milling the fused oxidic precursor of the industrial KM1 ammonia synthesis catalyst has also been studied. The results show that high‐energy ball‐milling offers some interesting possibilities for preparing novel
