CERIUM-ZIRCONIUM COMPOSITE OXIDE, PREPARATION METHOD THEREFOR AND USE THEREOF IN CATALYST |
摘要 |
Provided are a cerium-zirconium composite oxide, a preparation method therefor and a use thereof in a catalyst. The cerium-zirconium composite oxide has a composite phase structure, and comprises a cerium oxide phase and a cerium-zirconium solid solution phase, or consists of two or more cerium-zirconium solid solution phases with different crystal structures and different chemical compositions, wherein the chemical formula of the cerium-zirconium solid solution phase is CexZr1-x-yMyO2, where M is any one or more of a rare earth element other than cerium, a transition metal element and an alkaline earth metal element, x is 15-85 mol%, and y is 0-20 mol%. Due to the presence of two or more phases, the cerium-zirconium composite oxide has a relatively high high-temperature resistance and specific surface area, so that a catalyst prepared from the composite oxide has a good catalytic performance. |
