Abstract
Acidic zirconia materials have been tested as catalysts for the Selective Catalytic Reduction of nitrogen oxides (NOx) by ammonia (NH3-SCR). This paper focuses on the promotion of acidic zirconia by ceria. The introduction of ceria increases the NOx conversion, the selectivity to N2 and the durability and makes acidic zirconia materials attractive for Diesel after treatment systems.
