Abstract

In₂O₃-Ga₂O₃/Al₂ O₃ nanocomposite catalysts combined the advantages of good propene selectivity offered by Ga₂O₃/Al₂O₃ and high propene conversion provided by In₂O₃/Al₂O₃ to yield catalysts with excellent de-NO_x activity. A high NO conversion to N₂ of 80% was achieved over the catalyst with 2 wt% In and 8 wt% Ga. This NO conversion was attained even in the presence of 15% O₂ and 10% H₂O. The In₂O₃-Ga₂O₃/Al₂ O₃ nanocomposite remained active in the presence of SO₂. This combination of high activity, hydrothermal stability and sulfur resistance made our nanocomposite catalysts very interesting for applications in the selective catalytic reduction (SCR) of NO_x.
