The role of alumina in influencing the structural and chemical properties of the active phase supported on it is discussed using some effective alumina‐based lean NOx catalysts. These include Ag/γ‐Al2O3, CoOx/γ‐Al2O3 and SnO2/γ‐Al2O3. Alumina plays an important role in stabilizing Ag in the oxidic phase and cobalt in the 2+ oxidation state. For SnO2/γ‐Al2O3, alumina increases the SnO2 surface area. On both Ag/γ‐Al2O3 and SnO2/γ‐Al2O3, alumina also participates actively in the NOx reduction reaction. An active organic intermediate is formed on Ag or Sn oxide which reacts with NOx subsequently on alumina to form N2.
