Synthesis Methods and Influencing Factors of Metal Organic Framework Material MIL-53

Abstract Regarded as brand-new porous material, metal organic framework(MOF) has a certain ability to remove pollutants due to its high porosity, high specific surface area, adjustable micropore size and easy functionalization. Compared with other metal organic framework materials, MIL-53 has a relatively higher specific surface area and stronger hydrothermal stability, which leads to excellent performance and application prospects in the removal of pollutants. In this paper, synthesis methods of metal-organic framework material MIL-53 are introduced, and the influencing factors in the synthesis process using hydrothermal method are discussed, including the component ratio, type of organic solvent and pH value. Due to less dependence on residence time and organic solvent, mechanical method can reduce energy consumption and has latent value for future application. Among different influencing factors, reducing the pH of solution when synthesizing MIL-53 using hydrothermal method seems to save time and achieve rapid formation.
