This research is related to the synthesis of titanium dioxide nanoparticles (NpS TiO2) by the sol-gel method and its use as the solid interface to degradate 4-Nitrophenol (4-NP), an organic contaminant. Morphological, optical, and chemical characterization of the nanomaterial was carried out. The TiO2 photocatalytic activity was determined, using an initial concentration of 19.62 ppm of 4-NP, after 5 hours of reaction, it was possible to degrade 47.44 % of the 4-NP, the TOC decreased by 30% and the pH had a variation from
5.93 to 4.2. Based on the results, the degradation route for the 4-NP was determined.
