摘要：
A series of ceramic monolith (cordierite, corundum and mullite-cordierite) supported La0.8Ce0.2MnO3 catalysts for toluene oxidation were prepared and characterized to study the structure-activity relationship. The effects of loading and support were investigated by discussing the specific surface area, reduction ability, oxygen vacancies, and toluene oxidation efficiency. Finally, the optimum catalyst was obtained; when loading of La0.8Ce0.2MnO3 was 15 wt% and the carrier was cordierite, the catalyst exhibited the largest specific surface area (21.4 m(2).g-(1)) and best toluene conversion (T-50 = 167 degrees C, T-90 = 273 degrees C).
