Catalytic articles containing platinum group metals and non-platinum group metals and methods of making and using same

A catalytic article comprising

• a first catalytic coating comprising a platinum group metal supported on a first carrier, wherein the first carrier is selected from the group consisting of alumina, ceria, zirconia, ceria-zirconia composite, titania, and combinations thereof, 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 supported on a second non-zeolitic carrier, wherein the non-PGM metal comprises copper (Cu) and manganese (Mn), wherein the second non-zeolitic carrier comprises one or more of alumina, ceria, zirconia, ceria-zirconia composite, and titania, wherein the second catalytic coating comprises less than 1.5 wt. % platinum group metal;
• and
• one or more substrates,
• wherein the first catalytic coating is separated from the second catalytic coating.
