摘要：
A series of LaAl1-x FexO3/Al2O3/FeCrAl catalyst samples were prepared and characterized by X-ray diffraction and scanning electron microscopy. The catalytic activity of the catalyst samples for methane combustion was evaluated. The results indicated that the surface phase structure was LaAl1-xFexO3 perovskite-type oxide, alpha-Al2O3 and gamma-Al2O3. The surface particle shape and size of the catalyst samples varied with the molar ratio of Fe to Al. The catalytic activity of the catalyst samples for methane combustion was LaAl0.3Fe0.7O3/ Al2O3/FeCrAl > LaFeO3/Al2O3/FeCrAl > LaAl0.5Fe0.5O3/Al2O3/FeCrAl > LaAl0.7Fe0.3O3/Al2O3/FeCrAl > LaAlO3/Al2O3/FeCrAl.
