摘要
金属有机骨架材料(MOFs)是由有机配体和金属离子或团簇通过配位键自组装形成的具有分子内孔隙结构的有机-无机杂化材料,近年来在电化学、传感器、生物医学和催化等方面具有广泛的应用。尤其在催化领域,MOFs材料与传统无机材料相比,不仅具有极大的比表面积、高的孔隙率、可调节的孔结构,还包括3个重要的可改性部分:金属配位点、有机配体和纳米空腔。综述了MOFs材料作为催化材料的特点以及MOFs负载型催化剂构建方式及应用,并对金属有机骨架材料负载型催化剂的瓶颈问题进行了分析,对发展方向进行了展望。
Metal organic frameworks(MOFs)are organic-inorganic hybrid materials with intramolecular pores formed by the self-assembly of organic ligands and metal ions or clusters through coordination bonds,which have wide applications in electrochemistry,sensors,biomedicine and catalysis in recent years.Compared with traditional inorganic materials,MOFs not only have large specific surface area,high porosity,and tunable pore structure,but also include three important modifiable parts:metal coordination sites,organic ligands and nanocavities especially in the field of catalysis.In this paper,the characteristics of MOFs as catalytic materials and the construction methods and applications of MOFs-supported catalysts were reviewed.The bottleneck problems of metal-organic frameworks-supported catalysts were analyzed,and the development direction was prospected.
