| Abstract: | 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. |
