摘要:
The present disclosure describes rhodium iron catalysts of use in catalyst systems. Disclosed here are TWCs configured to include a substrate and one or more of a washcoat layer, an impregnation layer, and/or an overcoat layer. Disclosed herein are one or more of a washcoat layer and/or an overcoat layer formed using a slurry that includes one or more of an oxygen storage material, a refractory support oxide, iron, and rhodium. Disclosed herein are methods of preparing catalysts wherein a washcoat layer is deposited onto the substrate, one or more impregnation layers may be deposited onto the washcoat layer, one or more overcoat layers may be deposited onto the impregnation washcoat layer, and one or more additional impregnation layers may be deposited onto the one or more washcoat layers.
