摘要

摘要: 二氧化碳（CO₂）是一种主要的人为温室气体，主要由化学、热电和钢铁工业以及运输等部门产生。大气层中CO₂浓度的增加是导致诸多环境问题的主要原因，如全球变暖、海平面上升和全球气温升高。然而，CO₂作为一种可再生、廉价和无毒的化学原料，可用来生产具有高附加值的化学品，进而降低碳浓度。五元环碳酸酯由于其优越的物理化学特性，如高沸点、高偶极矩和生物降解等性能而被广泛应用。由环氧化合物和CO₂合成环碳酸酯是迄今为止研究较多的方法。然而，由于CO₂的高热稳定性和动力学惰性，使其作为反应原料需要大量的能量投入，可能导致的结果是CO₂浓度是一个净增长过程。因此，利用CO₂作为C1构筑单元是一个长期的挑战。本工作基于CO₂固定反应机制，概述了各种类型的均相和多相催化剂在CO₂固定反应合成精细化学品环状碳酸酯中的研究进展，包括有机催化剂、离子液体、金属有机框架化合物、多孔有机聚合物等。目前，几乎所有类别催化剂均可以在室温和低压力下，以实验室规模成功地使用纯CO₂将其固定到末端环氧化合物上，对于非末端环氧化合物通过更高的温度和压力以实现相应转化。同时，分析了催化剂在多取代环氧化合物或生物衍生环氧化合物转化、低浓度CO₂转化和实现工业化三个方面所面临的挑战，并提出了未来相关研究努力的方向。

Abstract: Carbon dioxide (CO₂) is a major anthropogenic greenhouse gas produced by chemical, thermoelectric and steel industries as well as transport sector. The increasing concentration of CO₂ in atmosphere is responsible for plenty of environmental problems such as global warming, rising sea levels and increasing global temperatures. However, CO₂ could consider as renewable, cheap and non-toxic chemical raw material, using CO₂ to produce high value-added chemicals to reduce carbon concentrations is a highly desirable strategy. Five-membered cyclic carbonates have a wide range of applications due to their superior physicochemical properties such as high boiling point, high dipole moment and biodegradability. The synthesis of cyclic carbonates from epoxides and CO₂ is by far the most approved method. Nevertheless, due to high thermal stability and kinetic inertness, it is necessary to activate CO₂ as feedstock for organic synthesis with large energy, which may result in the release of more CO₂ than is actually. Therefore, the use of CO₂ as C1 building block is long-term challenged. This paper outlines the progress of research on various types of homogeneous and heterogeneous catalysts for CO₂ fixation to generate cyclic carbonates, including organocatalysts, ionic liquids, metal-organic frameworks, and porous organic polymers. Almost all of these catalysts are currently available for the successful fixation of CO₂ to terminal epoxides on laboratory scale using pure CO₂ at ambient temperatures. For internal epoxides higher reaction conditions are usually required to achieve the desired conversion. It was analyzed three areas of present major challenges in catalyzing multi-substituted epoxides or bio-derived epoxides, diluted CO₂ conversion and industrialization, and the directions for future research efforts on the subject were suggested.
