1. A catalytic article comprising:
a) a first layer comprising a nickel component and a copper component supported on a ceria component, wherein the amount of the nickel component ranges from 0.1 wt. % to 30 wt. %, calculated as nickel oxide, based on the total weight of the first layer, and wherein the amount of the copper component ranges from 0.01 wt. % to 5.0 wt. % calculated as copper oxide, based on the total weight of the first layer;
b) a second layer comprising a platinum group metal component supported on one or more of an oxygen storage component, an alumina component, and a zirconia component, wherein the platinum group metal component is chosen from platinum, rhodium, palladium, and any combination thereof, and wherein the amount of the platinum group metal component ranges from 0.01 wt. % to 5.0 wt. % based on the total weight of the second layer; and
c) a substrate,
wherein the first layer and the second layer are separated by a barrier layer, and the barrier layer comprises alumina and the amount of loading of alumina in the barrier layer ranges from 0.25 g/in3 to 3.0 g/in3.
