具有多相催化性能的金属有机框架的研究进展

Research Progress on Metal-Orgainc Frameworks for Heterogeneous Catalysis

相比传统的多孔碳和无机沸石材料,金属-有机骨架(MOFs)具有制备方便、易于修饰、高孔隙率、比表面积大、框架规模大小可调等优点,在气体存储、吸附分离、多相催化、磁学等广泛应用.文章结合作者实验室的研究,介绍了MOFs作为多相催化剂所具有的独特特点;评估了MOFs作为催化剂的潜力,重点从MOFs的结构要素出发总结了MOFs作为多相催化剂的应用现状;讨论了MOFs作为多相催化剂需要重视的问题,为定向合成此类材料在催化方面的应用提供基础和理论价值.

Compared with the traditional porous carbons and inorganic zeolites, metal-organic frameworks （MOFs） have the advantages of convenient preparation, easy modification, high porosity, large specific surface area and ad- justable pore size, and have attracted extensive attention recently due to their potential applications in gas storage, adsorption and separation, heterogeneous catalysis, as well as magnetism. In this review, the unique advantages of MOFs as heterogeneous catalysis are firstly introduced. The potential of MOFs as catalysts are evaluated and the application status based on their structural elements are particularly summarized. Finally, we discuss the problems needed to be focused on, and provide meaningful experimental basis and theoretical value for the directional synthesis of these materials in catalysis.
