摘要：

Methane combustion over Pd catalyst supported on KIT-1 mesoporous material was investigated. The catalytic activity of the Pd catalyst was considerably improved by titania loading. The stability of the Pd catalyst to the exposure at high temperature is also enhanced by titania loading. Titania which is chemically bonded with the skeletal of mesoporous material interacts with palladium co-loaded and suppresses the decomposition of palladium oxide; more active phase in the methane combustion compared to palladium metal, resulted in the improvement in the catalytic performance of the Pd catalyst.
