The maximal formation rate of C2H4 was 0.264mmol·min−1·(g·cat.)−1 (48.0% C2H6 conversion, 92.2% C2H4 selectivity, 44.3% C2H4 yield) on 7wt% Co-BaCO3 catalyst at 650°C and 6000ml. (g·cat.)−1. h−1. Co-BaCO3 catalysts were comparatively characterized by XRF, N2 isotherm adsorption-desorption, XRD, H2-TPR and LRs. It was found that Co4+-O species were active sites on these catalysts in ODE with CO2. The redox cycle of Co-O species played an important role on the catalytic performance of Co-BaCO3 catalysts. On the other hand, the co-operation of BaCO3 and BaCoO3 was considered to be one of possible reasons for the high catalytic activity of these catalysts.
