Abstract

Se proporcionan compuestos catalizadores para automotores que tienen un material catalítico sobre un portador, donde el material catalítico comprende al menos dos capas. La primera capa se deposita directamente sobre el portador y comprende un primer componente de paladio soportado sobre un primer componente de óxido de metal refractario, un primer componente de almacenamiento de oxígeno o una combinación de los anteriores. La segunda capa se deposita sobre la parte superior de la primera capa y comprende un componente de rodio soportado sobre un segundo componente de óxido de metal refractario y un segundo componente de paladio soportado sobre un segundo componente de almacenamiento de oxígeno, un tercer componente de óxido de metal refractario o una combinación de los anteriores. Generalmente estos compuestos catalizadores se usan como catalizadores de(TWC). También se proporcionan los métodos para producir y usar los mismos.
