Abstract :

As a kind of newly emerged functional inorganic-organic hybrid material, Metal-organic frameworks (MOFs) have attracted increasing attention due to their tunable open metal centers, functional organic linkers, and active guest species in their pores. MOFs offer a new window for fine tuning various structureâ??property relationships to design MOFsbased catalysts with desirable performance. Recently, in order to obtain catalysts with excellent catalytic performance, good selectivity, high cyclic stability and convenient recyclability, we prepared a series of novel catalysts by designing and tailoring the composition and structure of MOFs, including immobilizing active guest species in the pores of MOFs, modifying the functional groups using a post-synthetic strategy, integrating MOFs with other functional materials or preparing 2D ultrathin MOFs, etc. These MOFs-based catalysts showed high efficiency for catalyzing the aerobic oxidation of alcohols and benzylic Câ??H bonds, oxygen evolution reaction (OER), etc. Meanwhile, the design concept and structure control of these novel MOFs-based catalysts are also highlighted.
