TiO2 nanoparticles codoped with iron and carbon were tested in a photocatalytic process using visible radiation to degrade Paracetamol from aqueous solutions. The studies performed for the characterization of the materials allowed us to verify the mesoporosity and crystallinity. Moreover, it was studied the effects associated with the recombination rate of the charge carriers responsible for the photocatalytic process. In this work, it was possible to verify the efficiency of a synergistic effect between iron and carbon when a calcination at intermediate temperature (150 ºC) was applied, which improves the response under visible light. With the solids treated at this temperature, the drug was completely degraded in just one hour of reaction, and the biodegradability of the samples was increased.
