- •
A series of CeO2–ZrO2–CrOx mixed oxides are prepared by co-precipitation method.
- •
Solid solution and more Ce3+ and Cr6+ species are formed by ZrO2 doping.
- •
Proper ZrO2 doping promotes 1,2-dichloroethane elimination on CeO2–ZrO2–CrOx.
- •
ZrO2 doping significantly improves the thermal stability of CeO2–ZrO2–CrOx.
- •
CeO2–ZrO2–CrOx exhibits good durability for 1,2-dichloroethane oxidation.
