    摘要: A catalytic converter for cleaning exhaust gas includes a first coating layer formed on a heat-resistant support, and a second coating layer formed on the first coating layer. The first coating layer contains alumina which supports palladium. The second coating layer contains Ce—Zr complex oxide which coexistently carries platinum and rhodium, and Zr—Ce complex oxide which differs in composition from the Ce—Zr complex oxide and which coexistently carries platinum and rhodium.
