Increasing concerns over global warming have prompted researchers to develop strategies that could minimize the emission of carbon dioxide from industries and power plants as a byproduct. Efficient strategies for the reduction of greenhouse gas emissions, primarily CO2, are needed. MOFs are a new and emerging class of porous material that have been dynamically investigated as catalysts for the synthesis of cyclic carbonates owing to its greater CO2 affinity. In this study, binary metal organic frameworks (MOFs) with HKUST-1 and UiO-66 have been synthesized using solvothermal method. The synthesized binary MOF is investigated for its catalytic efficacy in the synthesis of cyclic carbonates from epoxides and CO2. The UiO-66/Cu-BTC binary MOF provides high conversion rates of epoxides to cyclic carbonates with ＞99% selectivity under solvent-free conditions. The effects of reaction parameters such as catalyst amount, reaction time, CO2 pressure and reaction temperature were also studied in detail. Finally, a plausible reaction mechanism for binary MOF-catalyzed epoxide-CO2 cycloaddition reaction is also proposed. Keywords: Binary MOF, CO2 utilization, epoxide, cyclic carbonates. |
