Photo-fenton reaction for the decomposition of RR195 dye in the presence of the metal-organic polymer MIL-53(Fe<sup>3+</sup>) and a composite with graphene oxide

The metal-organic polymer of the composition Fe(OH)(BDC)×(H2O)2 – MIL-53(Fe) and the composite MIL-53(Fe)/GO (GO – graphene oxide) were obtained by the solvothermal method and characterized by X-ray diffraction and X-ray absorption and IR-Fourier spectroscopy, scanning electron microscopy. The presence of Fe2+ and Fe3+ ions in MIL-53(Fe) and MIL-53(Fe)/GO was established with a higher content of Fe2+ ions in MIL-53(Fe)/GO, which helps to increase the efficiency of the decomposition reaction of the RR195 dye, which is actively used in textile industry for dyeing fabrics in the photo-Fenton reaction.
