Three Y zeolites supported CeO₂ catalysts (CeO₂/USY, CeO₂/HY, CeO₂/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, N₂ adsorption/desorption and H₂-TPR. The results showed that the catalytic activity of the supported CeO₂ catalysts was much higher than that of Y zeolites, in particular, CeO₂/USY exhibited the highest activity, T_{98 %} values of DCE was about 270 ¡ãC. And the catalytic activity was strongly related to the interaction between CeO₂ and Y zeolites.
