Metal Organic Frameworks were built from [Fe3 (µ3-O) (COO)6] clusters and aliphatic di-carboxylate ligands such as pimelic acid, suberic acid, azelaic acid and sebacic acid which are isomorphic to so called established MIL-88A(Fe) namely Fe-MIL-88a-Pima, Fe-MIL-88a-Suba, Fe-MIL-88a-Azla and Fe-MIL-88a-Seba have been synthesized separately and characterized using PXRD, FE-SEM, BET, FT-IR. The as-synthesized Fe-MOFs have been demonstrated as efficient heterogeneous catalysts for both fenton and photo-fenton wet persulfate oxidation of Rhodamine-B solution and factors affecting the oxidation process were examined. Optimal conditions were examined for degradation of Rhodamine-B and the isomorphic substitution of longer organic linker chains in the MIL-88a improved the degradation efficiency. Fe-MIL-88a-Seba exhibited 99.9% degradation efficiency in 250 min and displayed good recyclability over four cycles. Overall, this work successfully demonstrates not only the ability to perform isomorphic substitution of various different aliphatic dicarboxylate linkers within MOFs but also the effect of the linker length substitution on the resulting catalytic performance.
