摘　　要：随着二氧化碳(CO2)排放量的不断增加,全球气候变暖及海洋酸化等问题也随之出现,因此,CO2的固定与转化已经成为当前科学家们研究的重要课题。利用CO2与环氧化物进行环加成反应制备环状碳酸酯就是其中一种有效的方法。金属有机骨架材料(metal-organic frameworks,MOFs)是一类由金属原子或原子簇与有机配体自组装形成的配位聚合物,由于其独特的结构特性与可设计的功能性质,使该材料在气体存储及分离、荧光传感、质子传导、生物医药以及催化等许多领域都展示出巨大的应用潜力。近几年,MOFs材料作为催化剂在CO2环加成反应中的应用越来越受到关注。从催化位点的类型及其作用原理出发,对近期MOFs材料在CO2环加成反应中的应用情况进行了总结与探讨。A series of abnormal climate phenomenon,such as global warming and ocean acidification,etc.,occur with the excessive emission of carbon dioxide(CO2),so the fixation and conversion of CO2 become an important and challenging research topic for scientists nowadays.The cycloaddition of CO2 and epoxide to cyclic carbonates is one of the effective methods of CO2 utilization.Metal-organic Frameworks(MOFs)is a kind of coordination polymer self-assembled by metal atoms or cluster and organic ligands.Due to its unique structural feature and devisable functional properties,MOFs shows great application prospects in many fields such as gas storage and separation,fluorescent sensor,biological medicine and catalysis.Recently,the catalytic applications of MOFs in CO2 cycloaddition have attracted more and more research attentions,herein,which are summarized and discussed from the type of catalytic sites and their work s mechanism.
