3MnO_x-1CeO_y (3Mn1Ce), a binary oxide with stoichiometric ratio of Mn/Ce = 3, is synthesized via hydrolysis driving redox. Compared to MnO₂, CeO₂, Cop-3Mn1Ce and Mixed-3Mn1Ce, the 3Mn1Ce catalyst exhibits better catalytic activity for toluene oxidation, which could be ascribed to higher concentration of active lattice oxygen, and better low-temperature reducibility, as well as homogeneous dispersion. In the test of substrate applicability, 3Mn1Ce displays good performances in the removal of benzene, o-xylene and chlorobenzene at moderate temperature. The application of high WHSV of 240000 mL/(g h) confirms the 3Mn1Ce catalyst still remains high efficiency to diminish toluene, giving the temperature at 280 °C for complete mineralization. A set of experiments under simulated realistic exhaust conditions demonstrate that 3Mn1Ce is a robust catalyst with high activity to oxidize mixed aromatic VOCs (BTX and chlorobenzene), satisfied endurability to high humidity (above 10–20 vol.% water) and good tolerance to severe change of reaction temperature. With characterization of XRD and TPR, the high performance is related to the homogeneous introduction of Ce resulting in higher structural stability and reversible reducibility. Moreover, the inner principle for oxidation of VOCs is revealed by comprehension of kinetic study.

通过水解驱动氧化还原反应合成了化学计量比为Mn / Ce = 3的二元氧化物3MnO _x -1CeO _y（3Mn1Ce）。与MnO ₂，CeO ₂，Cop-3Mn1Ce和Mixed-3Mn1Ce相比，3Mn1Ce催化剂对甲苯氧化表现出更好的催化活性，这归因于较高的活性晶格氧浓度，更好的低温还原性以及均相。分散。在基材适用性测试中，3Mn1Ce在去除苯，邻苯二甲醚方面表现出良好的性能。-二甲苯和氯苯，温度适中。高WHSV为240000 mL /（gh）的应用证实了3Mn1Ce催化剂仍然具有降低甲苯的高效率，使温度达到280°C即可完全矿化。在模拟的实际排气条件下进行的一组实验表明，3Mn1Ce是一种强大的催化剂，对混合芳香族VOC（BTX和氯苯）具有高活性，对高湿度（水含量在10–20 vol。％以上）具有良好的耐受性，并且对恶劣环境具有良好的耐受性反应温度的变化。通过XRD和TPR的表征，高性能与Ce的均匀引入有关，从而导致更高的结构稳定性和可逆的还原性。此外，通过对动力学研究的理解揭示了VOCs氧化的内在原理。
