Presently, we find a rapid pace of CO2 emission into the atmosphere causing major problems facing our planet. If no action is taken, it would have harmful consequences to humanity and the biosphere. More CO2 in the atmosphere will cause global warming. This will lead to climate upheavals disturbing the ecosystems, modification of the conditions and cycles of plant reproduction and numerous associated problems. Therefore, present CO2 content in the atmosphere should be drastically reduced to a much lower level on an urgent basis. Alternatively, CO2 represents an abundant C1 feedstock and its chemical utilization has caught the imagination of chemists in recent years. Thus, fixation of CO2 with epoxide to form cyclic carbonate (hereafter, CC) via cycloaddition reaction is significantly important and vigorously pursued in different laboratories around the world. This is because removal of CO2 takes place from the atmosphere and simultaneously it can be converted into value-added products. Metal organic frameworks (MOFs) have attracted enormous attention in recent years as potential systems for gas storage, separation, heterogeneous catalysis and so on, owing to their unique features such as designable architecture, controllable pore size, high surface area, permanent porosity, etc. In the present review, we discuss the recent progress made on catalytic conversion of CO2 to CCs by specially designed MOFs. It should be emphasized here that in the present review the literature survey is not exhaustive and we apologize for missing any important result in this review.

用于将CO 2化学固定为环状碳酸酯的金属有机框架

目前,我们发现向大气中排放CO 2的速度很快,这导致了我们星球面临的重大问题。如果不采取任何行动,将对人类和生物圈产生有害影响。大气中更多的CO 2将导致全球变暖。这将导致气候剧变破坏生态系统,改变植物繁殖的条件和周期以及许多相关问题。因此,应紧急将目前大气中的CO 2含量大幅度降低到更低的水平。另外,CO 2代表了丰富的C1原料,近年来其化学利用引起了化学家的想象。因此,CO 2的固定通过环加成反应与环氧化物形成环碳酸酯(以下称CC)非常重要,并在世界各地的不同实验室中大力推广。这是因为从大气中除去了CO 2,同时可以将其转化为增值产品。金属有机骨架(MOF)近年来由于其独特的特征(如可设计的结构,可控制的孔径,高表面积,永久孔隙率等)而成为潜在的气体存储,分离,多相催化等系统,引起了极大的关注。在本文中,我们讨论了在催化转化CO 2方面的最新进展。由专门设计的MOF移交给CC。在此应该强调的是,在本综述中,文献调查并不详尽,对于在本综述中遗漏任何重要结果,我们深表歉意。
