High catalytic efficiency in liquid‐phase oxidation of 1,4‐dioxane using a Pt/CeO 2 ‐ZrO 2 ‐SnO 2 /SBA‐16 catalyst
Source abstract
Abstract
A Pt/CeO 2 –ZrO 2 –SnO 2 /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 CeO 2 –ZrO 2 –SnO 2 , 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°C for 4 h, the residual percentage of 1,4‐dioxane reached 31%. Furthermore, the Pt/CeO 2 –ZrO 2 –SnO 2 /SBA‐16 catalyst exhibited high reusability and durability and the rate of net decrease in 1,4‐dioxane reached 44% at 80°C.
