Resumen

Titanium oxides (TiO₂) were synthesized by precipitation of titanium tetrachloride (TiCl₄) using ammonium hydroxide (NH₄OH). The synthesized materials were characterized by means of nitrogen physisorption, X-ray diffraction, infrared spectroscopy, U.V.-visible diffuse reflectance spectroscopy and the photocatalytic activity of the samples were measured by the degradation of the methyl orange. By means of this synthesis method we have doped the titanium oxide structure with nitrogen (N-TiO₂), stabilizing the anatase phase and obtaining mesoporous and nanocrystalline materials. The titanium oxide with higher specific surface area (132 m²/g) degraded the azo-compound to 100% in 180 min of reaction.
