Abstract
This invention is a method for preparing an automotive catalyst system. It comprises the steps of providing a substrate, providing a gamma-alumina support material, depositing a lanthana precursor and calcining the precursor, depositing an oxygen storage material precursor like ceria precursor and calcining this precursor material, and subsequently depositing catalytic material like platinum on the oxygen storage material. The alumina may be initially washcoated on the substrate or at any stage after deposition of the lanthana precursor.
