Loading metal guests within metal-organic frameworks (MOFs) via secondary functional groups is a promising route for introducing or enhancing MOF performance in various applications. In this work, 14 metal ions (Li, Na, K, Mg, Ca, Ba, Zn, Co, Mn, Ag, Cd, La, In, and Pb) have been successfully introduced within the MIL-121 MOF using a cost-efficient route involving free carboxylic groups on the linker. The local and long-range structure of the metal-loaded MOFs is characterized using multinuclear solid-state NMR and X-ray diffraction methods. Li/Mg/Ca-loaded MIL-121 and Ag nanoparticle-loaded MIL-121 exhibit enhanced H and CO adsorption; Ag nanoparticle-loaded MIL-121 also demonstrates remarkable catalytic activity in the reduction of 4-nitrophenol.
通过次级官能团将金属客体负载到金属有机骨架（MOFs）中是一种很有前途的方法，可以在各种应用中引入或增强 MOF 的性能。在这项工作中，使用涉及连接体上的游离羧酸基团的经济有效的方法，成功地将 14 种金属离子（Li、Na、K、Mg、Ca、Ba、Zn、Co、Mn、Ag、Cd、La、In 和 Pb）引入到 MIL-121 MOF 中。采用多核固态 NMR 和 X 射线衍射方法对负载金属的 MOFs 的局部和远程结构进行了表征。负载 Li/Mg/Ca 的 MIL-121 和负载 Ag 纳米粒子的 MIL-121 表现出增强的 H 和 CO 吸附性能；负载 Ag 纳米粒子的 MIL-121 在还原 4-硝基苯酚方面也表现出显著的催化活性。
