Three Y zeolites supported CeO 2 catalysts (CeO 2 /USY, CeO 2 /HY, CeO 2 /SSY) were prepared and used for deep oxidation of 1,2-dichloroethane (DCE) in low concentration (about 1,000 ppm). The catalysts were characterized by XRD, N 2 adsorption/desorption and H 2 -TPR. The results showed that the catalytic activity of the supported CeO 2 catalysts was much higher than that of Y zeolites, in particular, CeO 2 /USY exhibited the highest activity, T 98% values of DCE was about 270°C. And the catalytic activity was strongly related to the interaction between CeO 2 and Y zeolites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
