초록 ▼

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.

A method for preparing an automotive catalyst system, which comprises the steps of: providing a substrate; providing gamma-alumina support material; depositing lanthana precursor on said alumina support material from an aqueous solution of said precursor in an amount suitable to form a substantially atomic thickness layer of lanthana upon calcination of the precursor; calcining said lanthana precursor at a temperature of less than about 550°C. to convert said lanthana precursor to a substantially atomic layer of lanthana; depositing a layer of oxygen storage material precursor selected from the group consisting of ceria precursor, praseodymia precursor, and mixtures thereof on said lanthana layer; calcining said oxygen storage material precursor at a temperature of less than about 650°C. to convert said oxygen storage precursor to the oxide thereof; depositing at least a partial layer of catalytic material selected from platinum, palladium, or mixtures thereof on said oxygen storage material; and calcining said catalytic material at a temperature less than about 550°C. to form said automotive catalytic system. The method according to claim 1 wherein said aqueous solution of said lanthana precursor comprises a solution of a soluble lanthanum salt, said deposited lanthana precursor being calcined at a temperature between about 450°C. and about 550°C. forming lanthana.
