| Outline of Final Research Achievements |
The large pore size of bare γ-CD-MOFs is not conducive to efficient CO2 sorption. This is due to the decrease in Van der Waals forces as the pore size increases, resulting in less favorable sorption behavior. This study aimed to optimize synthesis parameters to achieve optimum CO2 sorption and tune the porosity of the MOFs. The optimized K-CD MOF achieved a CO2 sorption of 4.1 mmol/g at 273 K.
While applicant made progress in narrowing the larger pores by regulating synthesis parameters, applicant still believes that the much larger surface of K-CD MOF is yet to be explored.
