3D-printed polyamide structures coated with TiO2 nanoparticles, towards a 360-degree rotating photocatalytic reactor

3D-printed polyamide structures coated with TiO2 nanoparticles were obtained by a simple impregnation method. This novel type of 3D reactor was evaluated for its photocatalytic activity towards the degradation of methylene blue under UV light using a 360-degree rotating stage. Rotation improved the photocatalytic activity under UV light for all the 3D structures. The best photocatalytic structure showed a 94.1 % methylene blue degradation, after 180 min under UV irradiation with 360-degree rotation.
