The catalytic activity of the industrial catalyst A_110-3 after modification with Mn²⁺ was found to be increased to about 17.4%. The ammonia synthesis was carried out under conditions of 2.1 MPa, 14400 h^-1 and 300℃. The increase in activity is explained in terms of the weakness of Fe-N-N or Fe-N bond based on the XPS and TPD-MS results.
