合成了不同金属种类（M = Mn, Ce, Co, Fe）的MOx/ tio2复合材料，并将其用于苯的催化氧化。其中MnOx/ tio2的催化效率最高。研究了不同MnOx含量的MnOx/ tio2的催化活性。通过XRD、BET、SEM、TEM、XPS等表征手段分析了MnOx/ tio2催化剂的理化性质。此外，通过现场实验研究了苯在MnOx/ tio2上氧化的反应机理。
MOx/TiO2composites with various metal species (M = Mn, Ce, Co, Fe) were synthesized and employed as in the catalytic oxidation of benzene. Among those materials, MnOx/TiO2showed the highest catalytic efficiency. The catalytic activities of MnOx/TiO2with different MnOxcontents were also studied. XRD, BET, SEM, TEM, and XPS characterizations were conducted to analyze the physiochemical properties of the MnOx/TiO2catalysts. Moreover, the reaction mechanism of benzene oxidation over MnOx/TiO2was studied through the in situFTIRexperiments.
