简介 | The invention relates to a method of producing a catalysed particulate filter. The invention is characterised in that, in order to lower the particulate oxidation temperature, the filter is provided with a cerium oxide, a zirconium oxide or a cerium/zirconium mixed oxide which can also comprise at least one rare earth oxide other than cerium. The porosity of said oxide or mixed oxide is such that at least 80% of the pore volume comprises pores having a diameter of least 20 nm. |
