The effect of the insertion of silver ions on the photocatalytic activity of TiO2 was studied in this work, considering the degradation of tartrazine, a food coloring in the class of azo-compounds, with sulfonic groups in its structure, being highly soluble in water. Characterization techniques such as differential thermal analysis, x-ray diffraction, Raman Spectroscopy, difuse reflectance UV-Vis spectroscopy, surface area analysis, and scanning electron microscopy were used to understand the relationship between structure and photocatalytic activity for the oxides synthesized by homogeneous precipitation method in ultrasound, with different nominal concentrations of silver ions (0.0, 0.5, 2.0, and 5.0% m/m). According to the analysis by X-...
