  4. Abstract:
  5. In this paper, three metal-organic frameworks (Materials of Institut Lavoisier: MILs-100 (Fe)) as porous nanomaterials were synthesized using FeCl3, Fe(NO3)3 and Fe2(SO4)3 and denoted as MIL-100-1, MIL-100-2 and MIL-100-3, respectively. The synthesized MILs-100 (Fe) were characterized by FTIR, SEM, TEM, XRD, UV–vis DRS and zeta potential. Basic Blue 41 (BB41) was used as a model dye to study the photocatalytic dye degradation ability of the synthesized metal organic frameworks. The results showed that the synthesized nanomaterials decolorized BB41. The decolorization kinetics followed first-order kinetic model. The rate constant was 0.0034, 0.0041, 0.0091 and 0.0289 (1/min) for 0.01, 0.02, 0.03 and 0.04 g of photocatalyst. The data indicated that MIL-100-1 had higher photocatalytic activity. The photocatalytic activity of MIL-100 did not decrease significantly for three cycles. It can be concluded that the synthesized MILs-100 (Fe) could be used as alternative catalysts for photocatalytic decolorization of colored wastewater. © 2017 Elsevier Ltd
