Abstract A combined hydrothermal reaction and sequential chemical bath deposition method is developed for fabricating a Bi 2 S 3 modified single crystalline rutile TiO 2 nanorod array film on transparent conductive glass. The results indicate that the modification of Bi 2 S 3 nanoparticles extends the photoresponse of the Bi 2 S 3 /TiO 2 composite film into the visible light region, and enhances its photoactivity. The Bi 2 S 3 /TiO 2 film can serve as a photoanode in a photoelectrochemical cell and provide more effective photogenerated cathodic protection for 403 stainless steel in a corrosion cell with a 0.5 M NaCl solution under white or visible light illumination compared with the pure TiO 2 film.
