Abstract

Series of ordered mesoporous CexMn1-xOδ (x = 0, 0.1, 0.3, 0.5) were successfully prepared with a hard template method using KIT-6. Among the mesoporous CexMn1-xOδ catalysts, the rutile β-Ce0.1Mn0.9Oδ supports exhibited excellent catalytic activity for toluene oxidation. On basis of these, the effects of MOx (M = Co, Cu, Fe) on Ce0.1Mn0.9Oδ catalysts were investigated in the catalytic combustion of toluene. Among the as-prepared catalysts, the CuOx/Ce0.1Mn0.9Oδ exhibits the best performance of toluene catalytic combustion with the T90% of 254 °C and good stability.
