Anodic TiO2 nanotube (TNT) layers were prepared in eco-friendly fluoride-free organic-aqueous-based electrolytes containing cerium ammonium nitrate. Nanotubes with controllable morphology (tube diameter and tube length) and surface features (porosity and surface roughness) were obtained by varying percentual ratios of ethylene glycol (Ex%) and water (Wy%) in the electrolyte (Ex%Wy%). Obtained TNT layers were studied for photocatalytic degradation of methylene blue (MB) under UVA irradiation. The most promising, TNT layers were prepared in E75%W25% electrolyte with a thickness of approx. 1.9 μm with a tube diameter of approx. 33 nm, and exhibited the highest photocatalytic degradation rate (k = 0.0151 min−1).
