Summary: In this study, core-shell spheroid structure titanium dioxide/cadmium sulfide (TiO2/CdS) composites were synthesized as epoxy-based coating fillers using a simple hydrothermal method to improve the conversion and transmission efficiency of the photoelectron. The electrochemical performance of photocathodic protection for the epoxy-based composite coating on Q235 carbon steel surface was analyzed, showing significant photoelectrochemical properties. The modified composite coating extends absorption in the visible region and effectively separates photoelectron hole pairs to enhance the photoelectrochemical performance synergistically, with CdS acting as a sensitizer in the heterojunction system formed with TiO2.

Summary: A novel method for the synthesis of Bi nanospheres on the surface of BiOBr/TiO2 nanocomposites is proposed, which allows for controllable preparation of BiOBr/TiO2 and Bi/BiOBr/TiO2 heterojunction films. The synthesis temperature plays a key role in the formation of Bi nanospheres and the loading of BiOBr nanosheets. The structural and optical properties of the films are characterized, and the photocathodic protection performance of the prepared photoanodes under different solvothermal temperatures is systematically investigated. The introduction of Bi nanospheres enhances the photocathodic protection performance of the Bi/BiOBr/TiO2 photoanode, with the best performance observed at 160°C. Under visible light illumination, the Bi/BiOBr/TiO2 photoanode can significantly shift the potential of coupled stainless steel, demonstrating excellent photochemical stability and scouring resistance. The charge transfer mechanism for Z-scheme heterojunctions is proposed based on electron spin resonance characterization results, attributing the formation of Z-scheme heterojunctions to the bridging role of Bi nanospheres between BiOBr and TiO2 in the Bi/BiOBr/TiO2 films.

Summary: Using nanomaterials to design and prepare photoanodes can improve photoelectrochemical and photocathodic protection performances. This study focuses on the correlation between the detailed nanostructure and performance of a ZnO/TiO2 composite for the PCP of nickel-coated magnesium alloy. By manipulating the hydrothermal reaction temperature, a morphologically tunable nano-ZnO semiconductor was obtained, and the optimum photoelectrochemical and PCP capacities were achieved. The enhanced performance was attributed to the morphological regulation of nano-ZnO and the formation of staggered gap heterojunction between ZnO and TiO2.

Summary: Flower-like and bulk-like Co(OH)(2)-modified TiO2 p-n heterojunctions were successfully fabricated by a solvothermal method. The flower-like Co(OH)(2) microsphere-modified TiO2 showed better photoelectrochemical performance with narrower bandgap, upwardly shifted conduction band, and faster separation and migration of interfacial carriers compared to bulk-like Co(OH)(2). Additionally, the flower-like Co(OH)(2) microsphere-modified TiO2 photoelectrode exhibited effective photo cathodic protection for 304 stainless steel with a low photogenerated potential.

Summary: In this study, the photocathodic protection regulation mechanism of TiO2 nanofilms was explored by coupling size-dependent lattice distortion and stress engineering, using first-principles calculation and experiment. The results showed that uniaxial compression stress can effectively reduce the band gap of TiO2, thus improving its photocathodic protection performance. Low compression stress (Com'-TiO2) was confirmed to significantly enhance the photocathodic protection performance of TiO2. These findings offer a new approach for regulating the photocathodic protection performance of TiO2 nanofilms.

Summary: The adhesion of macrofouling organisms affects the integrity of steel, hindering its application in the marine industry. Corrosion forms of fouled steel were found to be different due to electrochemical processes, oxygen diffusion, ion transport paths, and secretion state differences. Localized corrosion occurred at the oyster/steel interface, while uniform corrosion occurred at the ascidian/steel interface. A micro-reaction mechanism was proposed to explain this phenomenon based on the effects of Cl-, anaerobic bacteria, enclosed space, and secretions.

Summary: Adherent macrofouling in marine environments leads to complex corrosion of steel surfaces, with localized corrosion at the oyster/steel interface and uniform corrosion at the ascidian/steel interface. Sulfate-reducing bacteria (SRB) play a key role in the microbiologically influenced corrosion (MIC) process at macrofouling-covered interfaces. Metagenomic techniques were used to study microbial communities and their response to macrofouling's coverage, revealing the growth of SRBs and the increase in FeS content at the oyster/steel interface, leading to severe localized corrosion.

Summary: In this study, a new antibacterial Zn composite coating was fabricated by electrodeposition of Fe3+-doped alkalized g-C3N4 (AKCN-Fe) into an existing Zn coating. The AKCN-Fe enhances the antibacterial property of the Zn coating under visible light due to its high photocatalytic performance, high loading content, and good dispersion. Scavenger experiments and electron paramagnetic resonance (EPR) measurements support the photocatalytic antibacterial mechanism of the composite coating, indicating the main role of superoxide (•O-2(-)) and the secondary role of hydroxyl radical (•OH).
