Abstract

Abstract : Porous Fe2 O3 architectures with controllable shapes are synthesized by the MOF-template method and show excellent catalytic activity for H2 S selective oxidation. Abstract : We report here a facile approach to tune the morphology of Fe-based metal–organic frameworks (MOFs) of MIL-53(Fe), in which acetic acid is used as a modulator to adjust the assembly directions of the MOFs. As a result, MIL-53(Fe) with controllable morphologies including spindle and short columnar shapes are synthesized. Following the pyrolysis of the MOFs, porous Fe2 O3 with preserved morphologies are obtained. Impressively, the synthesized Fe2 O3 exhibits enhanced performance in catalytic selective oxidation of H2 S to sulfur, with the morphologies showing an influence on the catalytic properties.
