Ir/Ce0.9M0.1O2 (M = Pr, Zr) catalysts showed more stable performance for MDR than Ir/CeO2. The metal-support interaction and oxygen defect of Ir/Ce0.9M0.1O2 (M = Pr, Zr) are improved. Ir sintering did not occur in the used catalysts. Performance decay was associated with the carbon deposition and sintering of supports.
