| titleOfInvention | Cerium-zirconium composite oxide and application thereof in catalyzing NOXApplication in reduction reaction |
| abstract | The invention provides a cerium-zirconium composite oxide, which comprises cerium oxide, zirconium oxide and at least one oxide of rare earth metal elements except cerium, wherein the pore volume of the composite oxide after heat treatment at 750 ℃ for 4-8h is 0.35-0.80 ml/g. The invention also provides application of the composite oxide and application of the composite oxide in catalytic reduction of NO X The method of (1). The cerium-zirconium composite oxide with a proper pore volume structure provided by the invention is in accordance with NO X Reduction reaction has good requirement on kinetic space and NO X Low temperature reduction activity, and can still maintain good catalytic effect after high temperature aging, and shows good NO X Removing effect and high-temperature aging resistant activity. |
