Patent Images
1. A catalyst system, comprising:
- a substrate;
a washcoat suitable for deposition on the substrate, comprising at least one oxide solid;
an impregnation layer, comprising at least one first catalyst; and
an overcoat suitable for deposition on the substrate, comprising at least one overcoat oxide solid selected from the group consisting of at least one of a carrier material oxide and at least one second catalyst;
wherein the at least one first catalyst comprises at least one spinel structured compound having the formula AB2O4, wherein each of A and B is selected from the group consisting of at least one of copper and manganese; and
wherein the at least one spinel structured compound is in mixed phase with at least one metal oxide.

Abstract
Variations of synthesis methods for Zero Platinum Group Metal (ZPGM) catalyst systems are disclosed herein. The methodologies of influence of synthesis methods on Cu—Mn catalyst systems which may include a variation of carrier metal oxides are disclosed. The XRD characterization and activity measurements of a series of stoichiometric and non-stoichiometric Cu—Mn spinels with different support oxide are discussed.
