Catalytic materials for passive soot oxidation and methods of their manufacture |
| abstract |
A catalytic material comprising ceria-metal oxide-alumina in a molar ratio of Ce:M:Al ions of from 75:25:100 to 25:75:100, wherein M represents zirconium or a zirconium at least partially substituted by a light lanthanide selected from the group consisting of lanthanum, praseodymium, neodymium and samarium. M may be neodymium and the catholic material may be heat-treated to more than 500°C and less than 1100°C. The catalytic material may be impregnated with 0.1-7.5% of copper by weight of the catalytic material. The catholic material may be a composite metal oxide having more than one phase, preferably a carbonate phase. The catalytic material may be formed into a catalytic composite and used as part of an exhaust gas treatment system for an internal combustion engine. The catalytic material may be manufactured by co-precipitation using potassium carbonate or cesium carbonate as the precipitating agent. The precipitate may be washed to remove potassium or cesium ions. |
