ZnCo2O4 prepared via the coprecipitation method showed an efficient bifunctional activity for both NOx reduction and 1,2-dichloroethane (DCE) oxidation. Compared with Co3O4 and ZnO, ZnCo2O4 catalyst showed best catalytic activity and stability in both NOx reduction and DCE oxidation. A maximum NOx conversion of 68.9% and complete DCE combustion were obtained at 300 and 400 °C, respectively. ZnCo2O4 catalyst exhibited the highest specific surface area (m2 g−1) and concentration of surface Co3+, which were considered as the main factors that determined its catalytic performance.
