Resumen:
TiO2 was synthesized by the sol-gel method, by hydrolysis of titanium isoproxide with water, usingcyclohexane as the dispersing medium. The titania was modified with Cr6 + ions, with concentrations of 0.5; 1.0; 1.5% m/m Cr. The materials were thermally treated at 400 °C and characterized by DiffuseReflectance (DRS), Raman Spectroscopy, Thermogravimetric (TG) and Thermodifferential Analysis(ATD), and Specific Surface. The photocatalytic activity was determined by studying the degradation ofan azo dye (yellow 5) and aromatic organic compound p-dihidroxybencene (hydroquinone) under visible light radiation. For both organic compounds, a higher photocatalitic activity is observed in doped solids.
