摘要：

A Pt/CeO2-ZrO2-SnO2/SBA-16 (SBA-16: Santa Barbara Amorphous No. 16) catalyst was developed for the efficient removal of 1,4-dioxane. Because the catalyst showed synergistic action between the high catalytic activity of Pt and the high oxygen release and storage abilities of CeO2-ZrO2-SnO2, high catalytic efficiency in the liquid phase was obtained in an air atmosphere without the supply of any strongly oxidizing additives or photoirradiation. After reaction at 80 degrees C for 4 h, the residual percentage of 1,4-dioxane reached 31%. Furthermore, the Pt/CeO2-ZrO2-SnO2/SBA-16 catalyst exhibited high reusability and durability and the rate of net decrease in 1,4-dioxane reached 44% at 80 degrees C.
