摘要：

A serial of Rux-Co3O4 (x = 0.1, 0.2 and 0.3) catalysts were prepared by the coprecipitation method and applied to the decomposition of N2O. They were characterized by the XRD, TEM, Raman, H-2-TPR, XPS, O-2-TPD and in situ DRIFTS. The results indicate that the strong interaction between Co and Ru exists in the Rux-Co3O4 catalysts, which results in much larger BET surface area, better structural stability and more surface Co2+, Ru3+ and oxygen species compared with Co3O4. Additionally, the Rux-Co3O4 catalysts, especial Ru0.2-Co3O4, show much higher activity and stability than the Co3O4 catalyst due to the synergistic effect of Ru and Co3O4. Moreover, the Ru0.2-Co3O4 catalyst shows much stronger resistance against 2.1% H2O and 1.5% O-2 in the feed than Co3O4. (C) 2017 Elsevier B.V. All rights reserved.
