Porous NH2-MIL-101(Fe) metal organic framework for effective photocatalytic degradation of azo dye in wastewater treatment.

The porous iron-based metal organic frameworks (NH2-MIL-101(Fe)), which consists of 2-amino benzene dicarboxylic acid (H2BDC-NH2) and ferrous ions were synthesized through one-step hydrothermal method. The surface area and pore volume of as-synthesized NH2-MIL-101(Fe) were 66.48 m2/g and 0.09 cm3/g, respectively. The excellent photocatalytic performance endows NH2-MIL-101(Fe) to generate hydroxyl radical (•OH), which then acting as efficiently active sites for azo dye degradation in wastewater. Meanwhile, the outstanding stability ability of NH2-MIL-101(Fe) indicates the potential candidate for wastewater treatment.
