CO2的过度排放导致全球环境问题日益严重,如何将CO2有效地利用起来成为全世界的研究热点。相比于高耗能的CO2捕获和储存(CCS)技术,通过催化反应将CO2转化为有价值的能源燃料是同时解决能源危机和环境问题的有效途径。其中,使用太阳能作为能量来源的光催化CO2还原技术更具应用前景。但是目前CO2光还原催化剂仍然存在很多缺点,如可见光响应能力低、光生电子空穴对复合严重、CO2吸附量小、产物的选择性低以及在含水环境中的产氢竞争反应等。金属-有机框架(MOFs)是由金属离子/簇和有机配体构成的一类独特的多孔晶态材料,具有可调的多孔结构、电子迁移速度快、CO2吸附量大等优点,在光催化CO2还原领域具有广阔的应用潜力。现有方法主要是通过对MOFs的功能化修饰、与其他功能型材料复合等获得高效的光还原CO2的催化性能。本文主要对近年来MOFs基CO2光还原催化剂(单一MOFs、MOFs基复合材料以及MOFs衍生材料)的研究现状进行了分析和讨论,并对MOFs材料在光催化CO2还原中的发展趋势进行了展望。

The effective use of CO2 has become a research hotspot worldwide, whose excessive emission led to increasingly serious global environmental problems. Compared with high energy-consuming CO2 capture and storage(CCS) technology, the photocatalytic conversion of CO2 into a valuable energy fuel is an effective way to solve energy and environmental problems. Among them, the development of a photocatalyst with efficient catalytic performance under visible light is the key to this process. Currently, there are still many shortcomings in photoreduction CO2 catalysts, such as weak visible light response ability, high recombination rate of photo-generated electron-hole pairs, low CO2 adsorption capacity, poor product selectivity, and hydrogen-evolution competition in an aqueous environment. Metal-organic frameworks(MOFs), with adjustable porous structures, fast electron migration rate, large CO2 adsorption capacity, etc., are a unique class of porous crystalline materials composed of metal ions/clusters and organic ligands, which have broad application potential in CO2 photocatalytic reduction. The existing methods improving the catalytic performance of MOFs-based catalysts is mainly to enhance the absorption of visible light by functional modification, formation of composites with other functional materials and so on. This review mainly analyzes and discusses the recent advances of MOFs-based photoreduction CO2 catalysts(single MOFs, MOFs-based composites and MOFs-derived materials), and predicts future development trends and prospects of MOFs-based materials in photocatalytic reduction of CO2.
