金属-有机框架基材料在二氧化碳光催化转化中的应用

Applications of Metal-organic Framework-based Material in Carbon Dioxide Photocatalytic Conversion

将大气中的二氧化碳(CO_(2))转化为燃料或高附加值化学品是降低大气中CO_(2)含量、减缓温室效应的有效途径之一.光催化CO_(2)化学转化条件温和,能耗低,在CO_(2)转化中占有重要地位.金属-有机框架(MOF)基材料由于具有比表面积大、光电性质优良和可调节性强等特点,是CO_(2)光催化转化的常用催化剂之一.本文综合评述了近两年MOF基材料在光催化CO_(2)还原反应、CO_(2)环加成反应和CO_(2)羧基化反应中的应用,阐释了MOF基材料在CO_(2)光催化转化中的优势和局限性,并展望了其未来发展.

Converting carbon dioxide(CO_(2))into fuels or high-additional-valued chemicals is an efficient route to decrease atmospheric CO_(2) concentration and mitigate green-house effect.Particularly,the photocatalytic CO_(2) conversion is of importance due to its mild reaction condition and low energy consumption.Metal-organic framework-based(MOF-based)materials are a kind of efficient catalyst for CO_(2) photocatalytic conversion owing to their unique features such as large specific surface area,good photoelectric properties and various tunability.In this article,the applications of MOF-based materials in CO_(2) photocatalytic reduction,cycloaddition and carboxylation in recent two years were reviewed.The advantages,limitations and future development of MOF-based materials for photocatalytic CO_(2) conversion reactions were discussed.
