چکیده انگلیسی
A series of the Ce1âxCuxO2âx/Al2O3/FeCrAl catalysts (x = 0-1) were prepared. The structure of the catalysts was characterized using XRD, SEM and H2-TPR. The catalytic activity of the catalysts for the combustion of methane was evaluated. The results indicated that in the Ce1âxCuxO2âx/Al2O3/FeCrAl catalysts the surface phase structure were the Ce1âxCuxO2âx solid solution, α-Al2O3 and γ-Al2O3. The surface particle shape and size were different with the variety of the molar ratio of Ce to Cu in the Ce1âxCuxO2âx solid solution. The Cu component of the Ce1âxCuxO2âx/Al2O3/FeCrAl catalysts played an important role to the catalytic activity for the methane combustion. There were the stronger interaction among the Ce1âxCuxO2âx solid solution and the Al2O3 washcoats and the FeCrAl support.
