MOFs催化剂的设计合成与应用研究进展

Research progress of design,synthesis and application of MOFs catalyst

根据金属有机框架材料(MOFs)催化剂活性位点的来源不同,将MOFs催化剂分为三大类:(1)MOFs上本身具有配位不饱和的活性金属节点,能够促进反应的进行;(2)形成MOFs的有机配体或者后合成修饰到MOFs上的官能团具有催化活性;(3)MOFs本身不起催化作用,只作为催化剂的载体,起到携带催化剂和阻止催化剂团聚和流失的作用。分别叙述了上述三类MOFs催化剂的合成方法,并对它们在有机反应中的催化活性、重复使用性和选择性等进行总结。

According to the sources of active sites of MOFs,MOFs catalysts are divided into three categories.1.The unsaturated metal nodes on the MOFs is activity,and could promote the reaction;2.The organic formation of MOFs and the functional groups modified in MOFs by post-synthesis have catalytic activity;3.MOFs themselves do not have a catalytic activity,and only serve as a carrier for the catalyst,and function to carry the catalyst and prevent the catalyst losing from MOFs.The synthesis methods of three types of MOFs catalysts were described separately,and summarized their catalytic activities,reusability and selectivity in organic reactions.
