Abstract (en)
[origin: WO2009112355A1] The composition of the invention comprises at least one supported oxide, based on a zirconium oxide, a titanium oxide or a mixed zirconium titanium oxide on a silica-based support. The composition is characterized in that, after calcination for 4 hours at 900 °C, the supported oxide is in the form of particles deposited on said support, the size of the particles being at most 5 nm when the supported oxide is based on a zirconium oxide, being at most 10 nm when the supported oxide is based on a titanium oxide and being at most 8 nm when the supported oxide is based on a mixed zirconium titanium oxide. The composition of the invention may be used as catalyst, especially for the selective reduction of NOx.
