CYCU-3: A mesoporous aluminum metal organic framework for the cycloaddition of epoxides and CO2 |
| 초록 |
Porous metal organic frameworks (MOFs) have been widely accepted as prominent materials for various applications including CO2 capture and transformations. The chemical fixation of carbon dioxide through cycloaddition reactions using various epoxides is a greener technique towards the synthesis of cyclic carbonates. In this work, a mesoporous metal organic framework [Al(OH)(SDC)] (CYCU-3) has been synthesized under solvothermal conditions. The mesoporous framework of Al-MOF consists of 1D inorganic chains linked by organic SDC ligands and displays high thermal stability up to approximately 300 °C. The role of Al3+ (from CYCU-3) and Br- ion (from TBAB) for the epoxide activation and ring opening of epoxide was studied for the cycloaddition reaction of CO2 and epichlorohydrin under ambient conditions. The CYCU-3 was found catalytically efficient towards CO2-epoxide coupling under ambient reaction conditions with high selectivity towards the desired cyclic carbonates under solvent free conditions. The effect of various reaction parameters were evaluated. A plausible reaction mechanism also was proposed. |
