摘要
用浸渍法将钙钛矿型复合氧化物成功地载于多孔陶瓷载体上．用ＸＲＤ分析了催化剂的晶相组成，对负载型和非负载纯钙钛矿相催化剂的催化活性作了对比研究．结果表明Ｌａ０．８Ｓｒ０．２ＭｎＯ３＋ｘ复合氧化物负载于多孔陶瓷上。
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.
