Effect of liquid-phase-deposited parameters on the photogenerated cathodic protection properties of TiO2 films

In this paper, the TiO2 films were prepared at different deposition parameters by the liquid phase deposition (LPD) method. The photoelectrochemical properties of the LPD-derived TiO2 films such as the open circuit potential (OCP) and the photocurrent spectra were also investigated. The results showed that the liquid-phase-deposited parameters had a significant influence on the photogenerated cathodic protection properties of the LPD-derived TiO2 films. It was observed that the most effective photogenerated cathodic protection for type 304 stainless steel (304SS) could be achieved when the TiO2 films were prepared from the solutions containing 0.03 M (NH4)2TiF6 and 0.09 M H3BO3 with the pH value of 2.90 at 80° C for 3 h.

► The TiO2 films were prepared at different deposition parameters by LPD method.
► The deposition parameters could affect the photocathodic protection of TiO2 films.
► The optimal liquid-phase-deposited parameters were determined in this paper.
