Abstract
The MnCeOx catalysts were successfully prepared using a two-step hydrothermal method with Ce-MOF as a template for the complete catalytic oxidation of toluene. The effects of different Mn additions, calcination temperatures, and preparation methods on the material properties were investigated. In addition, the resistance of the catalysts to chlorosis was investigated. The results demonstrated that the 3%MnCeOx-300 showed the best catalytic activity with T90 only at 215 °C. Furthermore, after 2 h of 1, 2-dichloroethane toxicosis, the catalyst still converted >90% of the toluene, demonstrating good activity and anti-chlorine poisoning ability. Characterization results proved that the high activity and stability of the 3%MnCeOx-300 catalyst are attributed to the highest specific surface area and the highest Ce3+/Ce4+, Mn3+/Mn4+, and Olatt/O ratios.
