Various amounts of Ag nanoparticles were successfully deposited in porous MOF-74Ni (or Ni/DOBDC) by an auto-reduction method. An optimized silver-loaded MOF-74Ni was shown to have an improved Xe adsorption capacity (15% more) at STP compared to the MOF without silver nanoparticles. The silver-loaded sample also has a higher Xe/Kr selectivity. These results are explained by the stronger interactions between polarizable Xe molecules and the well-dispersed Ag nanoparticles.
通过自还原法成功地在多孔 MOF-74Ni（或 Ni/DOBDC）中沉积了不同量的 Ag 纳米粒子。与不含银纳米粒子的 MOF 相比，优化后的负载银 MOF-74Ni 在 STP 下表现出更高的 Xe 吸附容量（增加了 15%）。负载银的样品还具有更高的 Xe/Kr 选择性。这些结果可以通过极化 Xe 分子与分散良好的 Ag 纳米粒子之间的更强相互作用来解释。
