Preparation of SnIn₄S₈/TiO₂ Nanotube Photoanode and Its Photocathodic Protection for Q235 Carbon Steel Under Visible Light.

ABSTRACT: TiO₂ is an attractive semiconductor suitable for photocathodic protection, but its weak absorption of visible light and low quantum yield limit its usage. Here, a new heterostructured SnIn₄S₈ nanosheet/TiO₂ nanotube photoanode was prepared and its photocathodic protection performance was analyzed. SnIn₄S₈ nanosheets were uniformly deposited on the surface of the TiO₂ nanotube via a solvothermal treatment. The SnIn₄S₈/TiO₂ composite exhibited better photocathodic protection performance compared with pure TiO₂ nanotubes, owing to its good visible-light response and photogenerated carrier separation efficiency. Moreover, the composite exhibited a maximum photocurrent densit
