1. A catalyst system, comprising:

  • a substrate;

    a washcoat suitable for deposition on the substrate, comprising at least one oxide solid selected from the group consisting of at least one of a carrier metal oxide, and a 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 metal oxide, and a catalyst;

    wherein at least one of the catalysts 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 a portion of the at least one spinel structured compound is stoichiometric; and

    wherein the at least one spinel structured compound is formed by calcination at a temperature in a range of about 300°

    C. to about 800°

    C.
