NH2-MIL-88B (Fe), (MIL = Materials of Institute Lavoisier) a mesoporous metal-organic framework (MOF) with high surface area was synthesized. The structural characteristics of NH2-MIL-88B(Fe) have exhibited an advantageous application potentialities in gas storage, separation and heterogeneous catalysis. This MOF is usually obtained by the hydrothermal synthesis in a Teflon-lined autoclave at high temperature (>150oC) under static conditions. However, this method exhibits several disadvantages such as high temperature, high pressure, long reaction time, and relatively low MOF yield. In this study, NH2-MIL-88B(Fe) has been successfully synthesized by using reflux method at low-temperature. Structure and properties of materials have been characterized by using: XRD, IR, SEM, TGA. The study has showed that NH2- MIL-88B(Fe) is as catalysts and the solution of trinitrotoluene (TNT) 50 ppm was decolorized after an hour under simulated sun-light radiation.
