| 摘 要： | 利用浸渍法制备了Ｌａ－Ｓｒ－Ｍｎ－Ｏ系负载型燃烧催化剂，ＸＲＤ相分析结果得到多在孔陶瓷载体表面形成了钙钛矿型氧化物Ｌａ０．８Ｓｒ０．２ＭｎＯ３，负载型和非负载型纯钙钛矿相催化剂二甲苯完全氧化活性数据表明，Ｌａ０．８Ｓｒ０．２ＭｎＯ３复合氧化物负载子多孔陶瓷上，不仅改善了催化剂的机械强度，共燃烧活性也得到显著提高。

| Abstract: | Crystalline phases of the supported La Sr Mn O catalysts for hydrocarbon combustion prepared by impregnation have been identified by X ray diffraction (XRD) analysis.The results show that perovskite type oxide La 0.8 Sr 0.2 Mn 0.3 is successfully formed on the surface of porous ceramics.The catalytic activities of the bulk and supported perovskite for xylene oxidation were studied comparatively,and supporting it on porous ceramics. |
