Abstract
|
The TiO2/CuO coatings were applied on pure titanium via PEO, observing the photocatalytic capacity for methylene blue (MB) degradation. Additionally, the effect of the ionization process at room temperature on the photocatalytic efficiency of the coatings was studied. A coating containing CuO nanoparticles (NPs) presented a more porous morphology. Phase analysis results proved that coatings containing CuO NPs were comprised of anatase and CuO phases, while the addition of ionized-CuO NPs into the electrolyte led to the formation of anatase, rutile, CuO, and TiP2O7
