Cover Story: To address the corrosion of 304 stainless steel in marine environments, TiO2/NiCo2S4 composite photoanodes were synthesized via anodic oxidation and hydrothermal methods. XRD, SEM, EDS, and XPS analyses indicated the growth of hexagonal NiCo2S4 particles on anatase TiO2 nanotube arrays, forming a type-II heterojunction. Ultraviolet–visible diffuse reflectance absorption spectroscopy showed that NiCo2S4 extended TiO2’s light absorption into the visible region. Electrochemical tests revealed that under visible light, the composite photoanode decreased the corrosion potential of 304ss to −0.7 V vs. SCE and reduced charge transfer resistance by 20% compared to pure TiO2. In conclusion, the TiO2/NiCo2S4 composite photoanode offers an effective approach for the marine corrosion protection of 304ss. View this paper
