This work addresses two distinct methods for titanium dioxide (TiO<sub>2</sub>) photocatalytic coatings preparation, that is, chemical –sol–gel, associated with spray coating– and electrochemical –anodic oxidation, which generates the oxide directly from a titanium substrate. Oxides are tested in the photocatalytic decomposition of tetracycline, an antibiotic commonly found in water. Both distilled and tap water are used as matrices. Coatings are tested multiple times to simulate real operating conditions, until photocatalytic activity is compromised. Life Cycle Assessment (LCA) is then used to quantify and compare the potential environmental impacts associated with the two different TiO<sub>2</sub> production strategies. Eventually, the assessment is completed by considering full photocatalyst regeneration: while for Sol–Gel this only implies cleaning and re-deposition, anodizing required oxide detachment, and subsequent re-anodization.
