Nb-Zr-Al-Mixed Oxide Supports for Rh Layer use in TWC Converters |
摘要 |
The present disclosure describes support oxides, including include Niobium Oxide, which are employed in three-way catalytic (TWC) systems. Disclosed herein are TWC sample systems that are configured to include a substrate and one or more of a washcoat layer, an impregnation layer, and/or an overcoat layer. The disclosed one or more of washcoat layer and/or overcoat layer are formed using a slurry that includes an oxide mixture and an Oxygen Storage Material. The disclosed oxide mixtures include niobium oxide (Nb2O5), zirconia, and alumina. Further, other disclosed oxide mixtures additionally include NiO. |

1. A catalyst system, comprising:
a substrate; a washcoat deposited on the substrate; and an overcoat; wherein at least one of the group consisting of the washcoat and the overcoat comprises about 20 (w/w) to about 80 (w/w) of an oxide mixture and 0 (w/w) to about 80 wt % of an oxygen storage material; and wherein the oxide mixture comprises about 1 (w/w) to about 25 (w/w) niobium oxide, about 1 (w/w) to about 60 (w/w) zirconia, and about 30 (w/w) to about 98 (w/w) alumina. |
