Lewis酸碱位点共存的MOFs在CO_(2)环加成反应中的催化应用

Catalytic Application of Lewis Acid-Basic Sites Coexisting MOFs in CO_(2)Cycloaddition

二氧化碳(CO_(2))是一种温室气体,同时也是丰富、无毒、不燃的可再生碳一资源,其转化和利用具有重要意义,CO_(2)与环氧化物环加成反应制备环状碳酸酯就是其中一种具有研究价值的途径。金属有机骨架材料(MOFs)由于具有可设计的模块化结构,在催化等领域一直以来都是研究热点。通过选择合适的有机配体与金属中心组装可以得到同时含有Lewis酸、碱位点的MOFs材料,能够在无助催化剂无溶剂条件下催化CO_(2)环加成反应。本文将以MOFs材料中Lewis酸、碱位点的类型为出发点来介绍含Lewis酸-碱对MOFs材料催化CO_(2)环加成的相关工作。

Carbon dioxide(CO_(2))is not only a kind of greenhouse gas,but also a widely existing,non-toxic and noncombustible renewable C1 resource,whose transformation and utilization are of great significance.The cycloaddition of CO_(2)and epoxide to cyclic carbonates is one of the ways of CO_(2)conversion with research value.Metal-Organic Frameworks(MOFs)have always been research hotspots in catalytic fields due to their designable modular structure.MOFs materials containing Lewis acid-basic sites can be obtained by selecting suitable organic ligands assembled with metal center,which can catalyze CO_(2)cycloaddition under co-catalyst-free and solvent-free conditions.Herein,some works about CO_(2)cycloaddition catalyzed by Lewis acid-base pair-containing MOFs are summarized and discussed from the type of Lewis acid-basic sites.
