Abstract The preparation method of FeO-based catalyst for ammonia synthesis has been studied. It is indicated that the contents of reducer should be more than 10% to obtain FeO as precursor. Also proper melting time and quick cooling rate will benefit both to control the ratio of Fe²⁺ and Fe³⁺ and raise the activity for ammonia synthesis.
Key words Ammonia synthesis catalyst, FeO, Prepare method
