Microfluidic Synthesis\nof Defective and Hierarchical\nPore Zr Metal–Organic Framework Materials and CO<sub>2</sub> Adsorption Performance Study

Microfluidic synthesis has emerged as a promising method\nfor synthesizing\nmetal–organic frameworks (MOFs). It overcomes the limitations\nof the traditional solvothermal method to regulate the structure and\nfunction of the MOFs. This study synthesized various MOFs with different\nstructures and functions by controlling the reaction time and the\nratio of metal ions to organic ligands through microfluidics and investigated\ntheir CO<sub>2</sub> adsorption properties. The results showed that\nthe microfluidic synthesized defective and hierarchical pore MOF-808\nimproved the adsorption performance of CO<sub>2</sub> by nearly 110%\nand 30%, respectively, compared with solvothermal synthesized MOF-808.
