摘要

將二氧化碳對人類生活環境的負面衝擊轉化為正面原料是綠色永續概念的積極具體作為。偶合二氧化碳與環氧化合物可產生高價值環狀碳酸酯和聚碳酸酯材料。目前最廣泛採用的偶合技術之一是使用金屬觸媒進行催化反應以增加生產效率和產品性質的調控性。金屬錯化物混成型材料具有傳統均相和異相觸媒的優點。本文將以搭載金屬錯化物的基材來分類介紹此類觸媒，其中主要包含氧化矽、碳材、磁性奈米粒子、和有機高分子等，同時也強調說明觸媒的可回收再利用能力。此外，透過此類觸媒於偶合反應的應用案例探討，也將呈現可能影響催化效果的因素。

It is a positive and concrete action for green sustainability that transforming the negative impact of carbon dioxide on the human living environment into useful raw materials. The coupling of carbon dioxide and epoxides could produce cyclic carbonates and polycarbonates, which are high-value materials. One of the most common technologies applied in the coupling reaction is the employment of metal catalysts due to their ability to increase the production efficiency and control the properties of the resulting product. The metal complex hybrid materials combine the advantages of both traditional homogeneous and heterogeneous catalysts. Herein, the description of this hybrid type of catalysts will be displayed based on the classification of the supports of the metal complexes, including silica, carbon materials, magnetic nanoparticles, and organic polymers. The recyclability of the catalysts will also be emphasized. Moreover, through the case study of the application of the hybrid catalysts toward the coupling reaction, the factors that might affect the catalytic performance will be presented.
