Abstract

γ-alumina-supported catalysts show promise as lean NOcursive Greek chi catalysts. 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 NOcursive Greek chi catalysts. These include Ag/γ-Al2O3, CoOcursive Greek chi/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 NOcursive Greek chi reduction reaction. An active organic intermediate is formed on Ag or Sn oxide which reacts with NOcursive Greek chi subsequently on alumina to form N2.
