The use of salts as grinding media to assist the mechanosynthesis, and the following one-pot mechanochemical post-synthesis, of hierarchically porous MOFs was carried out efficiently by ball milling. NaCl or KCl were used as a solid solvent to initially pre-grind with 1,3,5-benzenetricarboxylic acid (H3BTC) and copper acetate monhydrate, respectively, for 1 minute, then both mixtures were combined together for a further 20 minutes of grinding, and the resultant mixture was finally washed with ethanol and water to obtain the hierarchically micro-, meso- and macroporous HKUST-1 with a high yield. Moreover, the post-synthesis of these as-obtained hierarchically porous HKUST-1 was easily performed via grinding triethylenediamine (TED) with the above unwashed crude-products for 20 minutes. By adjusting the amount of NaCl and TED added, we simply fabricated the pore- and function-adjustable hierarchically porous HKUST-1. Furthermore, these as-obtained HKUST-1 products showed high performance in the capture of volatile iodine.
通过球磨有效地实现了使用盐作为研磨介质来辅助分级多孔金属有机框架（MOF）的机械合成以及后续的一锅法机械化学合成后处理。分别使用氯化钠（NaCl）或氯化钾（KCl）作为固体溶剂，先与均苯三甲酸（H3BTC）和一水合醋酸铜分别预研磨1分钟，然后将两种混合物合并再研磨20分钟，最后将所得混合物用乙醇和水洗涤，以高产率获得分级微、介和大孔的HKUST-1。此外，通过将三亚乙基二胺（TED）与上述未洗涤的粗产物研磨20分钟，可轻松实现这些所得分级多孔HKUST-1的合成后处理。通过调整NaCl和TED的添加量，我们简单地制备了孔径和功能可调的分级多孔HKUST-1。此外，这些所得的HKUST-1产品在捕获挥发性碘方面表现出高性能。
