Abstract:La 0.8 Sr 0.2 MnO 3 x ,a perovskite type mixed oxide, was successfully formed on the surface of porous ceramics by impregnation. The crystalline phases of the supported catalyst were identified by X ray diffraction(XRD). The catalytic activities of the bulk and supported perovskites for CO oxidation were studied comparatively. The results showed that the activity of La 0.8 Sr 0.2 MnO 3 x is increased greatly by supporting the perovskite on porous ceramics.
Keywords:supported  catalyst  perovskite  CO  oxidation
