文摘

•: 10% Mn/Fe–Ti spinel shows an excellent N₂ selectivity at low temperatures.
•: N₂O formation over 10% Mn/Fe–Ti spinel through the E–R mechanism is cut off.
•: NH₃ and NH₂ on 10% Mn/Fe–Ti spinel can be hardly activated by Mn⁴⁺ on the surface.
•: NH₃ activation is promoted due to the acceleration of Fe³⁺ regeneration by Mn⁴⁺.
