| 中文摘要: |
| 化石燃料的燃烧产生大量二氧化碳，引起了包括温室效应在内的诸多生态环境问题。二氧化碳作为一种重要的碳资源，也可用于制备多种重要的化工原料。环氧化合物与二氧化碳环加成是二氧化碳资源化利用的重要方向，并且产物环状碳酸酯在工业上能得到广泛利用。但二氧化碳具有惰性，不易被活化，因此寻求高效且稳定的催化剂成为实现二氧化碳快速转化的关键。金属有机框架（MOFs）具有不饱和金属位点、多孔性等优点被应用到各类催化反应中。又因其具有路易斯酸碱位点，对二氧化碳与环氧化物环加成反应有着突出的催化效果，所以在该反应体系中，也有着出色的表现，但反应条件比较苛刻。环氧化物的活化是在环加成反应中的重要环节，卤化物对环氧化物的活化有很好的效果，但是存在难回收的问题，卤化物阴离子还会引起含铁金属的腐蚀，在一定程度上限制了大规模的工业使用。很多研究人员致力于寻找减少使用该类助剂的方法，改进催化体系，于是催生了出关于MOFs改性的各类方法。本综述列举了在催化二氧化碳与环氧化物环加成反应过程中，关于MOFs的利用以及改性方法，并展望了MOFs材料在催化领域的发展前景。 |
| 英文摘要: |
| A large amount of CO2 is produced from the burning of fossil fuel, which is responsible for ecological and environmental problems, such as greenhouse. CO2 is a renewable source of carbon and can be used to produce a variety of important chemical materials. Cycloaddition of CO2 to epoxide is an important way for its utilization, and the product (cyclic carbonate) can be widely used in industry. However, CO2 is inert and not easily activated. Therefore, the search for efficient and stable catalyst becomes the key to achieve CO2 rapid conversion. Metal-organic frameworks (MOFs) with unsaturated metal sites and porosity have been used for all kinds of reaction. Meanwhile, MOFs with plentiful Lewis acid-base sites, have outstanding catalytic effect on the cycloaddition reaction of carbon dioxide and epoxide, so they also have excellent performance in the reaction system, but the reaction conditions are harsh. Activation of epoxides is an important step in the cycloaddition reaction, and halides have a good effect on the activation of epoxides, but they are difficult to recover. In addition, halide anions can cause ferrous metal corrosion, which is an issue for large-scale industrial implementation. Therefore, many researchers have been committed to finding ways to reduce the use of such additives, improve the catalytic system, and promote various methods on the modification of MOFs. This review lists the utilization and modification methods of MOFs in catalytic cycloaddition reaction of carbon dioxide and epoxide, and forecasts the development prospect of MOFs materials in the field of catalysis. |
