A study on the synthesis of MIL-100(Fe) and its application in the catalytic degradation of methylene blue

Abstract

In the present paper, a study on the synthesis of MIL-100(Fe) by hydrothermal process and its application in the catalytic degradation of methylene blue (MB) was demonstrated. The obtained samples were characterized by X-ray Diffraction (XRD), scaning electron microscope (SEM), Fourier-transform infrared spectroscopy (FT-IR), Brunauer, Emmett and Teller (BET) and energy-dispersive X-ray spectroscopy (EDX). The results showed that the synthesized MIL- 100(Fe) exhibited high crystallinity and surface area. Its catalytic activity was evaluated by measuring the rate of conversion of MB after oxidation reaction by H2O2. The results indicated that the MIL-100(Fe) showsed high catalytic activity for the oxidation reaction of MB and at pH = 10, MB was degraded almost completely after after 3 hours of presence of the catalyst.
