Abstract: In this study, iron doped MIL-53(Al) metal-organic framework material (denoted as Fe/MIL-53(Al)) was prepared by hydrothermal method. The obtained materials were characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetry analysis (TG), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), and N2 adsorption/desorption isotherms. The influence of iron content on the structure of MIL-53(Al) and treated temperature of Fe/MIL-53(Al) were investigated. The results showed that the obtained Fe/MIL-53(Al) synthesized at mole ratio of Fe/Al = 1/9, still maintains many structural properties of the MIL-53 material, and the iron element was evenly distributed over the entire area of the material. The treatment at 280 ºC had almost no effect on the metal-organic framework structure of the material. The pore of the material was cleared at the treated temperature of 350ºC; therefore, the specific surface area of the material increased significantly.
