Abstract

Aspects of the invention pertain to catalytic articles and methods of making catalytic articles comprising a first catalytic coating comprising a platinum group metal, wherein the first catalytic coating is substantially free of Cu, Ni, Fe, Mn, V, Co, Ga, Mo, Mg, Cr and Zn; a second catalytic coating comprising a non-PGM metal, wherein the second catalytic coating is substantially free of any platinum group metal; and one or more substrates, wherein the first catalytic coating is separated from the second catalytic coating, optionally with a barrier layer.
