Abstract
The oxidation of NO to NO2 was investigated on Co–Ce–Zr solid solutions prepared by the sol–gel method An improvement of the catalytic activities of the samples was observed for Cocontained catalysts compared to Ce–Zr solid solution The ZCCo036 catalyst exhibited more than 50 NO conversion rate in the temperature range from 250 to 350 °C The chemicophysical properties of catalysts were characterized by XRD Raman spectroscopy BET XPS and NOTPD The results indicated that the introduction of cobalt into the lattice of Ce–Zr solid solution increased the amount of Ce3+ and facilitated the oxygen mobility The features may be responsible for the improving of catalytic activities of Co–Ce–Zr metaloxides for NO oxidationThis work was financially supported by the National Natural Science Foundation of China U1162119 and 51078185 IndustryAcademia Cooperation Innovation Fund Projects of Jiangsu Province BY2012025 and the Scientific Research Project of Environmental Protection Department of Jiangsu Province 201112
