摘      要：Carbon dioxide(CO_(2))is the main greenhouse gas,whereas it is also a nontoxic,abundant,cheap carbon and oxygen *** copolymerization of CO_(2) with epoxide presents a sustainable approach to the synthesis of biodegradable polymers,which upcycles the waste into *** complex catalyst plays the central role in the reaction,since it provides oxophilic and Lewis acidic active center both for monomer activation and chain end stabilization,and nucleophiles as Lewis base for ***,heavy metal catalyst with certain toxicity such as cobalt undisputedly dominates the copolymerization catalysis which comprises the overall *** circumvent the potential environmental hazard,developing highly active catalyst composed of green metals is of great importance especially when the polymer was utilized for agriculture *** work reviews the development of sustainable metal catalysts for the production of CO_(2) copolymer,centered by Al,Mg,Ti,Fe,generally acknowledged as low toxic,environmentally benign,biocompatible,and also abundant in earth s *** is placed in recent five years where several historic examples are also included to construct a full picture of the sustainable catalysis explored to date.
