摘要
自从1969年日本的井上祥平(Shohei Inoue)教授发现二氧化碳共聚物以来,二氧化碳共聚反应经历了50年的此起彼伏的发展历程,诞生了基于非均相催化与均相催化的二氧化碳高分子化学,而近期不断涌现的基于二氧化碳共聚物的生物降解塑料产品和工业化活动,预示二氧化碳基塑料正处于大规模工业化的前夜.尽管从二氧化碳制备生物降解塑料体现了废弃资源高值化利用与环保塑料产品的双重价值,但催化剂的活性与选择性始终是制约二氧化碳基塑料大规模工业化的主要因素.为此,本文以催化剂设计为基础,从精准催化、环境友好、协同催化三个角度梳理了二氧化碳共聚反应催化剂的发展脉络,分析生物降解二氧化碳基塑料研究领域所面临的挑战和机遇,并展望了其未来发展前景.
The last five decades have witnessed the rapid progress of CO2 copolymer science since the pioneering work of Shohei Inoue, which gave birth to carbon dioxide polymer chemistry based on design of heterogenous and homogeneous catalysts for carbon dioxide copolymerization. The increasing industry activity from CO2-based plastics indicates the era for new generation biodegradable plastics is coming. Although the preparation of CO2 based biodegradable plastics have benefits both for the utilization of waste resources and the production of environmental friendly materials, the lack of active and selective catalysts has always been the key factors impeding the large-scale industrialization of CO2-based plastics. This review focuses on the precise catalytic chemistry in CO2 copolymers,drawing a catalyst developing roadmap based on perspectives of precise, environmental-benign and cooperative catalysis, and pointing out the opportunities and challenges in this area.
