Preparation process of photocatalysts, photocatalysts obtainable by the same and photodegradation method that uses them. The present invention consists of a process for obtaining photocatalysts based on carbon gels structured in microspheres, which are highly doped on the surface with titanium oxide using new synthetic routes. These, materials that photocatalytically active under visible radiation or have better performance in the uv. Also described are photocatalysts obtainable by said process as well as a photodegradation process, in particular for the photodegradation removal of contaminants that said photocatalysts employ under ultraviolet and visible radiation.

La presente invención consiste en un procedimiento de obtención de foto-catalizadores basados en geles de carbón estructurados en microesferas, que son altamente dopados en superficie con óxido de titanio empleando nuevas rutas de síntesis. Estos, materiales que fotocatalíticamente activos bajo radiación visible o presentan mejores prestaciones en el UV. También se describen foto-catalizadores obtenibles por dicho procedimiento así como un procedimiento de fotodegradación, en particular para la eliminación por fotodegradación de contaminantes que emplea dichos foto-catalizadores bajo radiación en el espectro ultravioleta y visible.
