In order to reduce mankind's carbon footprint and thus reducing the environmental toll of human activities, it is necessary to implement industrial technologies to convert carbon dioxide in added-value products, from which polycarbonates represent an important category. This review discusses the development of catalytic systems for the ring-opening copolymerization (ROCOP) of epoxides and CO₂ to produce polycarbonates, focusing on those systems made from earth-abundant metals. Since the ROCOP of epoxides and CO₂ commonly proceed through a multinuclear mechanism, this account focuses only on bi- and multimetallic heterogeneous catalytic systems developed from 1985 onwards and homogeneous catalysts reported after 2015, giving emphasis on the structural features of these complexes and their corresponding reactivities.

为了减少人类的碳足迹，从而减少人类活动对环境造成的损失，有必要实施工业技术，将二氧化碳转化为附加值产品，聚碳酸酯是其中的一个重要类别。这篇综述讨论了环氧化物和 CO ₂开环共聚 (ROCOP) 催化系统的发展，以生产聚碳酸酯，重点是那些由地球上丰富的金属制成的系统。由于环氧化物和 CO ₂的 ROCOP 通常通过多核机制进行，本文仅关注 1985 年以后开发的双金属和多金属多相催化体系以及 2015 年之后报道的均相催化剂，重点介绍这些配合物的结构特征及其相应的反应性。
