Iron-based crystals with uniform size was successfully synthesized by using a microwave-assisted solvothermal method and characterized by XRD, FE-SEM, DRS and BET. We also investigated the photocatalytic activity of MIL-53(Fe) for the decomposition of methylen blue using H2O2¬ as electron acceptors. By using the microwave-assisted method, the small crystalline materials with high yield was prepared at lower temperatures and in shorter reaction time comparing with conventional electric heating. From DRS results, MIL-53(Fe) samples displayed the absorption spectrum up to the visible region so their activity was better than commercial TiO2-P25 materials. And because of the higher surface area of smaller particle size, MIL-53(Fe) was synthesized by the microwave method performed to be useful for photocatalytic reaction. |
