Photoelectrocatalytic degradation of chlortetracycline using Ti/TiO2 nanostructured electrodes deposited by means of a Pulsed Laser Deposition process

► Ti/TiO2 was prepared by means of a PLD method and used in the PECO process. ► The deposited TiO2 coatings were found to crystallize in the rutile phase. ► Current intensity and time were the main parameters influencing CTC oxidation. ► Current intensity and time contributions on CTC removal are 76.2% and 16.7%. ► The PECO process applied under optimal conditions oxidized 74.2 ± 0.57% of CTC.
