Photoelectrochemical applications for a corrosion prevention of stainless steel using solar energy to minimize the losses cause by corrosion and to increase the economic value, become interesting topic recently. In this study, TiO2 nanotube (TiO2 NT) were synthesized by anodizing method to maximize its activity for corrosion prevention performance under UV light exposure. The TiO2 NT films were synthesized by anodization of titanium metal in electrolyte containing water, glycerol and fluoride ion, followed by calcination at 500 oC. Variation of anodizing voltage and calcination temperature were conducted to obtain a good TiO2 NT films. The produced TiO2 NT films were characterized by SEM, XRD, Surface Area Analyzer and electrochemical work station. The results showed that typically a highly ordered TiO2 NT with mostly anatase phase and having mesoporous character were obtained. During corrosion test, it was observed that the photopotential Misriyani et al shifted to the more negative value i.e. from -0,332V to -0,440V for stainless steel coupled with TiO2 NT films. This result indicated that the TiO2 NT, which was arranged in a photo-electrochemical manner, could prevent the corrosion of stainless steel.
