Abstract

Abstract : A new Fe-based MOFs catalyst was used for benzene hydroxylation with the high phenol yield (64.5%) and selectivity (92.9%). Abstract : A new Fe-based metal–organic framework (MOF), termed Fe-TBAPy Fe2 (OH)2 (TBAPy)·4.4H2 O, was solvothermally synthesized. Structural analysis revealed that Fe-TBAPy is built from [Fe(OH)(CO2 )2 ]∞ rod-shaped SBUs (SBUs = secondary building units) and 1, 3, 6, 8-tetrakis( p -benzoate)pyrene (TBAPy 4− ) linker to form thefrz topological structure highlighted by 7 Å channels and 3.4 Å narrow pores sandwiching between the pyrene cores of TBAPy 4− . Consequently, Fe-TBAPy was used as a recyclable heterogeneous catalyst for benzene hydroxylation. Remarkably, the catalysis reaction resulted in high phenol yield and selectivity of 64.5% and 92.9%, respectively, which are higher than that of the other Fe-based MOFs and comparable with those of the best-performing heterogeneous catalysts for benzene hydroxylation. This finding demonstrated the potential for the design of MOFs with enhancing catalysis activity for benzene hydroxylation.
