A robust and porous Zr metal-organic framework, sal-MOF, of UiO topology was synthesized using a salicylaldimine (sal)-derived dicarboxylate bridging ligand. Postsynthetic metalation of sal-MOF with iron(II) or cobalt(II) chloride followed by treatment with NaBEt3H in THF resulted in Fe- and Co-functionalized MOFs (sal-M-MOF, M = Fe, Co) which are highly active solid catalysts for alkene hydrogenation. Impressively, sal-Fe-MOF displayed very high turnover numbers of up to 145000 and was recycled and reused more than 15 times. This work highlights the unique opportunity of developing MOF-based earth-abundant catalysts for sustainable chemical synthesis.
使用源自水杨醛亚胺（sal）的二羧酸桥联配体合成了具有 UiO 拓扑结构的坚固多孔 Zr 金属有机骨架 sal-MOF。通过后合成的金属化与氯化铁（II）或氯化钴（II）随后用 NaBEt3H 在 THF 中处理，得到了 Fe 和 Co 功能化的 MOF（sal-M-MOF，M = Fe，Co），它们是烯烃加氢的高活性固体催化剂。令人印象深刻的是，sal-Fe-MOF 表现出高达 145000 的非常高的周转数，并且已经回收和再使用了 15 多次。这项工作突出了开发基于 MOF 的丰富地球催化剂用于可持续化学合成的独特机会。
