| titleOfInvention | Three-way catalyst used for automobile emission purification and preparation method thereof |
| abstract | The invention relates to a three-way catalyst used for automobile emission purification and a preparation method thereof, and belongs to the field of atmospheric pollution regulation and environment-friendly catalytic materials. The catalyst uses a cordierite honeycomb ceramic as a carrier, a mixture coating of Gamma-Al2O3 and rare earth complex oxide (Ce-Zr-M-Ox) as a promoter, and transition metals of Co and Ni, and precious metals of Pd and Rh as catalytic activity components. According to the invention, through the adoption of a sol method, the pre-treated carrier is coated with the promoter coating, the carrier coated with the promoter coating is dipped into a precursor complex solution of catalytic activity components by using an equal-volume dipping method, and the catalyst is obtained through drying and roasting. The three-way catalyst has low precious metal content; the transition metals of Co and Ni have well concerted catalysis with the precious metals; higher three-way catalytic activities and excellent low temperature ignition performances are shown; carbon monoxide, nitrogen oxide, and hydrocarbon in automobile exhaust can be effectively removed; the preparation process of the catalyst is simple. |
