Catalytic combustion is an efficient and economic technology to eliminate toluene, and CeO2 shows very good performance in this kind of reactions. In this work, three kinds of CeO2 catalysts with different morphologies (rod, hollow sphere and cube) have been prepared, and there performances for toluene catalytic combustion were compared. It is found that CeO2-HS shows the best catalytic activities for toluene degradation. Toluene conversion could get 90% at 207 degrees C. That's because CeO2-HS catalyst have largest surface area and most oxygen vacancies, which are vital for toluene catalytic oxidation. CeO2-HS also shows very good catalyst stability, reusability and excellent tolerance to water.
