dc.description.abstractIn this work, two well-known titanium-type metal–organic framework (MOF) solids named MIL-125 and MIL-125-NH2 were successfully synthesized using a solvothermal method. The structure of the catalytic materials was confirmed by X-ray powder diffraction, infrared spectroscopy, N2 adsorption–desorption measurements, thermogravimetric analysis and UV–Vis diffuse reflectance spectroscopy analysis. An azo dye, Congo red, was used as model pollutant to study its photocatalytic activity under UV–Vis light irradiation. A comparison with the commercial TiO2 P-25 revealed both the beneficial effect of the porous structure of MOFs and the influence of the –NH2 group on the light activation process. Formation of hydroxyl radicals (·OH) by catalysts was evaluated by luminol degradation probing. Finally, the titanium MOF catalysts can be recycled and reused without significant loss of activity.spa
