本文采用浸渍法制备了以MOx（ M为Cu、Co、Zn、Fe、Ce）和MnOx混合氧化物为活性组分，堇青石蜂窝陶瓷为载体的有机废气催化燃烧催化剂，以甲苯作为探针反应物测定该类催化剂的催化燃烧活性。考察了M与Mn物质的量比等因素对甲苯催化燃烧性能的影响，深入进行了XRD、BET和SEM表征与分析。实验结果表明：Fe/Mn物质的量的比为4：1，焙烧温度为500℃，催化剂具有最佳的催化燃烧活性。

A series of M( M为Cu、Co、Zn、Fe、Ce)-Mn-O complex oxides catalysts supported on cordierite were prepared by an impregnation method. Catalytic performance of the catalysts were investigated by catalytic combustion of toluene and the structure of the catalysts was characterized by XRD、SEM and BET measurements. The effects of the preparation parameters including the M( M为Cu、Co、Zn、Fe、Ce)/Mn ratio was researched. The results show that the catalyst with Fe/Mn molar ratio of 4/1 and roasting temperature 500℃ exhibits the highest catalytic performance.
