| 英文摘要 | A series of Sm-Mn oxides (SmMnO3 , SmMn2O5 and Sm0.9Ag0.1Mn2O5) of perovskite-type and mullite crystal phases were synthesized for the catalytic oxidation of CO and C3H8. The Sm0.9Ag0.1Mn2O5 composition showed the highest catalytic activity among the series of solids, especially for the CO oxidation to CO2 with T50 and T90 values of 60 and 95 degrees C, respectively. The catalysts were characterized by powder XRD, Raman, BET, XPS, and H-2 - TPR. It was found that the catalytic performance of the solids was correlated well with their redox properties. Synergetic effects between Ag-related species and the mullite phase resulted in more active surface oxygen species and remarkably lowered the reduction temperature of the Sm0.9Ag0.1Mn2O5 solid. |
