Abstract

In this study, the UiO-66-NH₂ material was successfully synthesized via the solvothermal method under conditions of 120 °C and ambient pressure. The UiO-66-NH₂ material was characterized using X-ray Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDX), and the Brunauer-Emmett-Teller (BET) surface area analysis method. The characterization results confirm that the UiO-66-NH₂ material has a particle size of approximately 50–100 nm, a surface area of 344 m²/g, a pore volume of 0.204 cm³/g, and a band gap energy of 2.65 eV. The UiO-66-NH₂ material demonstrated the capability to reduce 80.8% of Cr(VI) and 78.4% of Methylene Blue (MB) after 120 and 180 minutes of visible light irradiation under optimal conditions, respectively. The factors influencing the removal of Cr(VI) and MB, including catalyst dosage, initial concentration of Cr(VI) or MB, and pH value, were also investigated.
