High Performance of NO Oxidation Over Co/Zr0.2Ce0.8O2 Catalysts Prepared by One-pot Method
2018
Cobalt supported on Zr0.2Ce0.8O2 with different cobalt loading for catalytic oxidation of NO to NO2 were prepared by the one-pot method using citric acid as complexing agent. The samples were characterized by XRD, H2-TPR, O2-TPD and NO-TPD and the catalytic performance was investigated. The results showed that the Co/Zr0.2Ce0.8O2 catalyst containing 10 wt.% of Co3O4 exhibited excellent activity at a wide temperature window ranged from about 240 °C to 380 °C with NO conversion above 50%. The high catalytic performance of Co/Zr0.2Ce0.8O2 samples should be attributed to the active component related with cobalt species.
