| titleOfInvention | Catalyst composition containing base metal oxide-promoted rhodium |
| abstract | A catalyst composition comprising a monolithic carrier coated on the reverse side with a coating. Said coating comprises a catalytic material consisting of rhodium and a basic metal oxide activator dispersed on a zirconia support activated by ceric oxide, for example a hybrid ceric oxide-zirconia support. A refractory metal oxide, such as activated alumina, can be incorporated into the coating to increase its adhesion to the support. The presence of a quantity stabilizing rhodium, for example 1 to 5 or 10% by weight of the hybrid support, of the basic metal oxide activator dispersed with the rhodium on the zirconia support activated by ceric oxide makes it possible to reduce unwanted sintering of rhodium. The limited amount of ceric oxide, for example from 1 to 25% by weight of the weight, for example, of the hybrid ceric oxide-zirconia support, reduces the detrimental effect on the health of rhodium when it is very deeply dispersed on a support. containing ceric oxide. A method using the catalyst composition for the three-way conversion of automobile engine exhaust gas is described. |
