CO2 is an advantageous C1 feedstock as it is abundant, inexpensive and common industrial waste. One useful method to add value to CO2 is by its ring-opening with epoxides to synthesize cyclic carbonates. Cycloaddition is attractive in terms of CO2 utilization as it is catalytic, yields valuable products already used and sold, and results in significant carbon dioxide uptake. Metal-organic frameworks (MOFs) are versatile material formed from organic linker which connect metal. MOFs are prospective candidates in CO2 conversion catalyst owing to their rich Lewis acid/base sited and functional group. We report the catalytic efficiency of indium based MOF, denoted as CPM-200. The catalysts was characterized using a various physicochemical analysis, including XRD, XPS, ICP-OES, EA, FE-SEM, TGA, FT-IR, and BET. The catalytic activity of CPM-200 was analyzed in the synthesis of cyclic carbonate from epoxide and CO2, and it was shown that CPM-200 operated in synergy effect with co-catalyst tetrabutylammonium bromide (TBAB) under solvent-free conditions. Several reaction parameter studies were carried out to find the optimal condition. Finally, a plausible reaction mechanism was suggested. |
