Investigation of Synthesis Solvent for Large-Pore Stabilized MIL-53 Compounds with Increased CO2 Adsorption and Decreased Water Adsorption

摘要

In order to understand the effect of solvent on MOF synthesis and CO2 adsorption properties, a well-studied MOF system must be chosen. MIL-53 is one of the most famous MOFs, with wide investigation into its gas adsorption properties. However, the study of MIL-53 has largely centered on its ability to undergo a large structural transition in the presence of certain guest molecules, leading to promising application in gas adsorption and chemical sensing. While the breathing transition has been probed extensively, the effect of solvent on the synthesis of the material and its breathing behavior is not well studied. Furthermore, MIL-53 has been synthesized with various metal nodes, positioning it as an excellent choice for the analysis in this work as it allows for the elucidation of solvent effects on the structural transition, metal center interactions, and gas adsorption performance.
