The current state of knowledge of iron catalysts used in ammonia synthesis
A review with 78 refs. covering the mechanism of redn. and deactivation of iron catalysts in terms of a catalyst model with the active iron atom surface assumed to be wetted by promoters oxides. Promoters join with the Fe atom via O atom. At > 350 degrees C, chem. equil. is rapidly attained in the nanocryst. systems.
