Abstract CeO2-coated Pd core-shell units with thin shell was synthesized and supported on mesoporous alumina via electrostatic method. The effect of high temperature pretreatment on the transformation of Pd species was investigated. The results revealed that CeO2-coated Pd nanoparticles were highly dispersed on mesoporous alumina, resulting in a 90% CH4 conversion at 392 °C. The catalyst pretreated at 600 ℃ was found to possess the best sintering resistance performance for CH4 oxidation and the final combustion temperature was as low as 570 °C. During the aging process of catalyst, the formation of Ce1-XPdXO2-δ solid-solution interface could effectively retard the decomposition of PdO and agglomeration of Pd species, consequently enhancing the catalytic performance of the material.
