MONTALVO-ROMERO, Carlos et al. Degradation of paracetamol with a rotating disc photoreactor using TiO₂ catalysts doped with metallic nanoparticles. Acta univ [online]. 2025, vol.35, e4449.  Epub Jan 26, 2026. ISSN 2007-9621.  https://doi.org/10.15174/au.2025.4449.

In this work, the performance of the rotating disk photoreactor with a TiO2 semiconductor used as a photocatalyst in its crystalline form and doped with iron (Fe3+) and silver (Ag+) metallic nanoparticles (NP) in the heterogeneous photocatalysis process for paracetamol degradation is reported. The photocatalyst was impregnated in the discs, and the doping with Fe3+ and Ag+ nanoparticles was carried out using the photo deposition technique. The photocatalysts were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the efficiency in the degradation of toxic compounds presents a high removal of the pollutant at low concentrations.

Keywords : Paracetamol; TiO₂ -based photocatalysts; rotating disc photoreactor.
