摘要： A three-way catalyst composition, and its use in an exhaust system for internal combustion engines, is disclosed. The three-way catalyst composition comprises rhodium, a cerium-containing oxide, and a supported palladium component. The supported palladium component comprises palladium, barium, and cobalt and alumina. The three-way catalyst composition shows improved light-off performance.
