| Outline of Research at the Start |
The research aim is to synthesis a novel polymer coated MOF sorbent to be used for CO2 capture applications. The internal and external active sites of sorbent material could help extensive CO2 sorption. Besides, the coating could improve the stability of MOF during sorption and regeneration cycle.
|
| 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.

| Academic Significance and Societal Importance of the Research Achievements |
The project resulted a CO2 sorbent with high surface area and high sorption capacity, using green and sustainable precursor materials. It could advance the field of carbon capture and contribute to sustainable solutions for mitigating CO2 emissions and promoting environmentally friendly practices.
