Abstract

SnO₂/TiO₂ nanorods (TNRs) composite film was successfully fabricated. The results showed that the SnO₂ nanoparticles were deposited onto the surface of the TNRs film, and this composite film exhibited excellent light absorption ability. Meanwhile, the SnO₂/TNRs composite film exhibited the superior photoelectrochemical performance. With white light illumination, this composite film made the potential of the coupled 304 stainless steel (304SS) in a 0.5 mol·L⁻¹ NaCl solution drop by 240 mV, exhibiting more efficient photocathodic protection (PCP) effect. What's more, it could provide delay protection for the steel in darkness attributing to the “electron pool” effect of SnO₂.
