Abstract (en)
[origin: WO2010076509A1] The invention relates to a structure for filtering a gas emitted by a diesel engine and laden with gaseous pollutants such as nitrogen oxides NOx and solid particles, such as a particle filter, characterised in that said filtering structure includes a catalytic system including at least one noble or transition metal suitable for reducing NOx and a carrier material, wherein said carrier material includes or is made of zirconium oxide partially substituted by a trivalent cation M3+ or by a divalent cation M'2+, said zirconium oxide being in a reduced state, with a sub-stoichiometric oxygen content.
