ABSTRACT

The involvement of CO₂ as a renewable and abundant feedstock toward a carbon balanced future has led to production of several value-added products. The primary focus in the current effort is to assess fixation of CO₂ and epoxides into cyclic carbonates by employing state-of-the-art metal complexes as promising catalytic systems. Our attention is restricted to Earth-abundant metals such as aluminum, cobalt, iron, zinc and few transition metals in association with different ligand skeletons used for the structural construction of the respective complexes. This review sequentially categorizes these complexes and provides a panoramic overview of their selective catalytic activities and mechanistic understandings based on experimental and theoretical evidences.

摘要

CO ₂作为一种可再生且丰富的原料，朝着碳平衡的未来发展，导致了多种增值产品的生产。当前工作的主要重点是通过采用最先进的金属配合物作为有前途的催化系统来评估将 CO _{2和环氧化物固定到环状碳酸酯中。}我们的注意力仅限于地球上丰富的金属，如铝、钴、铁、锌和少数过渡金属，这些金属与用于构建相应配合物的不同配体骨架有关。本综述按顺序对这些配合物进行分类，并基于实验和理论证据对它们的选择性催化活性和机理理解进行了全景式概述。
