摘　　要：The catalytic activity of the industrial catalyst A 110 3 after modification with Mn 2+ 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 NN or Fe—N bond based on the XPS and TPD MS results.The catalytic activity of the industrial catalyst A 110 3 after modification with Mn 2+ was found to be increased to about 17.4%.
