| Summary: | The invention provides a powdered catalyst material based on aluminum oxide, which contains at least one basic metal oxide and at least one noble metal from the platinum group of the Periodic Table of Elements, as well as aluminum oxide. The catalyst according to the invention has outstanding thermal stability with a high surface area and a high, aging-stable dispersion of the catalytically active components. It is particularly suitable for the production of catalysts for the treatment of exhaust gases from internal combustion engines.
A powdered catalyst material based on aluminum oxide, which contains at least one basic metal oxide and at least one noble metal from the platinum group of the Periodic Table of Elements in addition to aluminum oxide. The catalyst material is obtainable by loading a support material already stabilized by basic oxides by renewed impregnation with further basic oxides. After drying and calcining this post-impregnated material at temperatures below ° C., the catalytically active noble metals are also incorporated into the support material by impregnation. |
