| titleOfInvention | Anti-aging cerium-zirconium composite oxide and preparation method and application thereof |
| abstract | The invention provides an anti-aging cerium-zirconium composite oxide with the thickness of at least 80m 2 Specific surface area per gram, pore volume of 0.55-0.80 ml/gram, 500-1200 mu mol O 2 Oxygen storage per gram, and pore diameters distributed in a double pore group distribution, wherein the diameter of the first pore group is concentrated in the range of 3 to 10nm, and the diameter of the second pore group is concentrated in the range of 15 to 80 nm. The cerium-zirconium composite oxide provided by the invention shows remarkable anti-aging activity and better low-temperature catalytic activity, and can be used for catalyzing hydrocarbon, carbon oxide and/or nitrogen oxide in mobile source tail gas. The preparation method of the cerium-zirconium composite oxide provided by the invention does not use a surfactant, reduces sewage discharge, is more green and environment-friendly, can recover the ionic liquid and the absolute ethyl alcohol by simple distillation, greatly reduces the cost, is particularly suitable for industrial production, can obtain the composite oxide with more uniform element lattice doping distribution and no phase separation, and has great significance for research on a mobile source tail gas treatment purifying agent containing the cerium-zirconium composite oxide. |
