Summary: CuInSe2 nanoparticles were successfully deposited on the surface of TiO2 nanotube arrays (NTAs) to form CuInSe2/TiO2 composites with enhanced visible light absorption and high photoelectric conversion efficiency. These composites demonstrated the photocathodic protection (PCP) capability for metals, with a significantly decreased potential of 316 SS and a four times higher photocurrent density compared to TiO2 NTAs. The protective effect of the composites lasted for more than 8 hours in the dark state after 4 hours of visible light illumination, attributed to increased visible light absorption, extended lifetime of photogenerated electrons, and generation of oxygen vacancies.

Summary: The use of new photocathodic protection technology to protect 304 stainless steel has attracted significant attention from corrosion researchers due to the severe consequences of metal corrosion on resources and economy. However, the photocatalytic materials used for protection still have some defects, such as high recombination rates and inefficient transfer of photoinduced electrons. In this study, PbS quantum dots modified TiO2 nanotubes were successfully synthesized and showed improved photocurrent density and optical absorption compared to pure TiO2, providing effective photocathodic protection for stainless steel under visible light irradiation.

Summary: The photoelectrochemical cathodic characteristics of amorphous and nanorod ZnO thin-film coatings on stainless steel AISI 304 substrates were investigated. The results showed that the current densities increased and voltages decreased with UV light exposure for both types of coatings. The cathodic mechanism was explained by the photogenerated electron-hole pairs, hole consumption, and electron transfer.

Summary: A series of muscovite/TiO2 heterostructures were prepared using the sol-gel method for photocathodic protection of 304 stainless steels. The effects of different mass ratios of muscovite to TiO2 on the properties of TiO2 and muscovite/TiO2 heterostructures were studied. The corrosion resistances and photoelectrochemical properties of the 304SS coated with muscovite/TiO2 heterostructures were evaluated.

Summary: Single-step anodization of titanium foils in ethylene glycol based electrolytes with chrome alum has been used to synthesize chromium doped TiO2 nanotubes for efficient photocathodic protection of 403 stainless steel. The concentration of chrome alum in the electrolyte affects the performance of the photoelectrodes. The photocurrent density of the best chromium doped TiO2 nanotube electrode was significantly higher than the undoped sample, providing more negative open-circuit potential for efficient photocathodic protection of stainless steel under light irradiation.
