Abstract: Provided herein are zoned catalysts that utilize components efficiently in that relatively short zones are provided to achieve specific functionalities to convert and/or trap one or more components in the exhaust stream. Highly controlled zoned are formed from one end of a monolithic carrier. The zones have a flat profile such that the zoned catalytic material within each passage of the substrate is at a substantially uniform distance from one end of the carrier. Methods of making and using the same are also provided.
