Photocatalytic degradation of trinitrotoluene using material Fe-NH₂-BDC (MOF)

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