Abstract: This study aimed to synthesize and characterize an iron-perylene metal-organic framework (MOF) as a photocatalyst for the degradation of tetramethylthionine chloride in the presence of hydrogen peroxide. Iron-based MOF with perylene-3,4,9,10-tetra carboxylate (PTC) ligands was produced through a solvothermal technique and was characterized for its morphology, optical properties, surface area, thermal stability, and electrochemical behavior. The results showed that Fe-PTC MOF had a tubular crystalline structure with an average crystal size of 51 nm, a bandgap energy of 1.94 eV, and was responsive to visible light. Thermal analysis revealed a significant weight loss of 63.53 percent between 390 °C and 490 °C due to the decomposition of the organic linker, with an exothermic heat release of 5.97 J/mg. Electrochemical characterization showed an onset oxidation potential of 0.641 V (vs. Standard Hydrogen Electrode (NHE)) and a calculated Lowest Unoccupied Molecular Orbital (LUMO) energy level of -1.299 V, indicating potential applications in photocatalytic and photovoltaic technologies. Photocatalytic activity tests demonstrated that the degradation of tetramethylthionine chloride followed pseudo-first-order kinetics, and optimization using Response Surface Methodology (RSM) identified the optimal conditions for degradation: 1.5 mg of photocatalyst, 0.2 M H2O2 concentration, and 133 min of contact time. These results underscore the effectiveness of Fe-PTC MOF in treating dye-contaminated textile wastewater under illumination with visible light."
