The present study reports the titanium dioxide (TiO₂) films synthesized from TiCl3 precursor on ITO glass substrates using two electrochemical techniques, namely direct electro-deposition (DE) and pulse electro-deposition (PE). The synthesis potential during the time-on (Ton) period was fixed at -1.5 V. However, the open-circuit potential was applied during the time-off (T_off) period. The effect of the technique of electro-deposition and Toff duration on the properties of TiO₂ films and their photoelectron-catalytic activity were investigated. The obtained films were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-VIS spectrometer, and photocurrent measurement respectively. It is found that the use of the PE technique at different T_off improves the properties of TiO₂ films compared to the DE technique. The XRD patterns show the anatase phase with a marked preferential orientation along the (101) direction for all samples. From the SEM analysis, it is seen a significant change from big multigrain agglomerates at DE to a dense film structure and small multigrain agglomerates at different Toff. As the Toff decreases from 3 s to 1 s, the photocurrent response rises and reaches a high value of about 12 mA/cm². Compared with DE, and under UV light the photocatalytic property of TiO₂ film synthesis via PE has been improved in the degradation of methyl orange (MO). Finally, the films deposited at low T_off (T_off =1 s) show a faster degradation of MO.
