摘　　要：以十六烷基三甲基溴化铵(CTAB)为模板剂,采用水热合成法制备了稀土金属离子Ce掺杂的六方相有序介孔材料Ce-MCM-41,并用N2吸附、XRD、FT-IR、UV-Vis对样品结构进行了表征,将该材料用于模拟太阳光(500W氙灯)照射下甲基紫和亚甲基蓝两种染料的光催化降解研究,研究结果表明,该材料能显著降解上述两种染料,光催化降解效率高达82.4%和75.4%,具有很好的应用和开发前景。Cerium-doped hexagonal ordered mesoporous material Ce-MCM-41 was prepared by hydrothermal method using CTAB as structure-directing agent. The structure of the material was characterized by nitrogen adsorption, XRD, FT-IR and UV-Vis spectroscopy. The Ce-MCM-41 was used for the photocatalytic degradation of methylene blue, methyl violet under simulated sunlight irradiation. It was found that the catalyst exhibited good activities of photocatalytic degradation of methylene blue （82.4%）, methyl violet （75.4%） under simulated sunlight irradiation, has a good application and development prosprects.
