Series of MnO_x catalysts were synthesized through oxalate route and calcined at facile temperatures. Characterizations through XRD, N₂-adsorption/desorption, HRTEM, C₆H₆-TPD, O₂-TPD, XPS, and H₂-TPR revealed that MnO_x calcined at 250 °C (N250) with a main crystal phase of Mn₂O₃ showed micro-mesopores and largest specific surface area, and therefore had a high adsorption capacity of C₆H₆. N250 also presented better oxygen mobility, rich surface adsorbed oxygen species (O_ads), and proper ratio of surface Mn⁴⁺/Mn³⁺. The starting temperature of H₂-TPR of N250 was the lowest among the obtained MnO_x samples. As a result, N250 exhibited the lowest T₉₀ value of 191 °C in C₆H₆ thermal catalytic oxidation (WHSV 60,000 mL g_cat.⁻¹ h⁻¹, initial C₆H₆ concentration 190 ppm) among all the catalysts, and this T₉₀ value is lower than those reported in many research. At last, a potential reaction pathway was proposed according to the results of in-situ FTIR measurement.

通过草酸盐路线合成了一系列MnO _x催化剂，并在适宜的温度下煅烧。通过XRD，N _2-吸附/解吸，HRTEM，C ₆ H ₆ -TPD，O ₂ -TPD，XPS和H ₂ -TPR进行表征，结果表明MnO _x在250°C（N250）下煅烧，主晶相为Mn ₂ O ₃表现出微中孔和最大的比表面积，因此具有高的C ₆ H ₆吸附能力。N250还具有更好的氧迁移率，丰富的表面吸附氧种类（O _ads）和适当的表面Mn ⁴⁺比/ Mn ³⁺。在所得的MnO _x样品中，N250的H ₂ -TPR的起始温度最低。其结果是，N250表现出最低Ť ₉₀值191℃在C ₆ H ^ ₆热催化氧化（WHSV 60000毫升克_猫。^-1  ħ ^-1，初期的C ₆ ħ ₆浓度190ppm的）中的所有催化剂中，并且该T ₉₀值低于许多研究报告的值。最后，根据现场FTIR测量结果提出了潜在的反应途径。
