Titanium dioxide nanotubes (TiO2-NTs) have drawn attention for their electrical, optical, photocatalytic properties, and biocompatibility. In this study, TiO2 nanotubes with diameters ranging from 65 to 100 nm were synthesized using the hydrothermal method and characterized physically, chemically, and biologically. Additionally, they were used as catalysts in the photodegradation of the azo dye Orange II, achieving a degradation rate of 97% at pH 8, with 1.5 g/L H2O2 and an initial dye concentration of 25 ppm.
