A catalyst composition comprising at least one first support, at least one first precious metal component, at least one second support, and at least one second precious metal component. The total amount of the first precious metal component comprises from 1 to 99 weight percent based on the total of the first and second precious metal components. The average particle size of the second support is greater than the average particle size of the first support. The present invention includes a method to prepare the catalyst composition and a method to use the catalyst composition as a three-way catalyst. The composition results in a coated layer from a slurry where the more supported first precious metal component is in the bottom half and more supported second precious metal component is in the top half.
