摘要
Catalysts for methane combustion were prepared by Fe supported on γ-Al2O3?ZrO2-Al2O3?YSZ-Al2O3,respectively.The results indicated that among these three kinds of catalysts Fe2O3/YSZ-Al2O3 has showed the highest activity and best thermal stability.The XPS results demonstrated that the addition of ZrO2 and Y2O3 can decrease the interaction between iron species and γ-Al2O3 support,and prevent Al2O3 transmitting to the surface of catalyst.
