| 中文摘要: |
| 制备了一系列碘改性的含铜介孔复合氧化物催化剂，并利用XRD、N2吸脱附、H2-TPR和元素分析对其进行了表征.以O2为氧化剂，以甲苯氧化反应为探针，测试其催化性能，结果表明复合氧化物载体的元素组成显著影响催化剂的性能.在最优反应条件下，无需添加有机溶剂，甲苯转化率可达25.6%，主产物苯甲醛选择性为100%.进而将催化剂应用于其他苯系物（苯、乙苯、二甲苯）的氧化反应，也取得了较好的催化效果，且该催化剂可以循环使用多次. |
| 英文摘要: |
| A series of iodine modified copper-containing mixed oxides were prepared and characterized by XRD, N2 sorption, H2-TPR and elemental analysis. The catalytic performance of the obtained catalysts was firstly investigated in the selective oxidation of toluene with O2 used as oxidant. It was found that the elemental composition of copper-containing catalysts played important roles in their catalytic performance. Under the optimum reaction conditions, in absence of any organic solvents, the conversion of toluene could reach 25.6% with 100% of the selectivity to bezaldehyde. In addition, the catalysts could be reused for several times. |
