Graphitic carbon nitride (g-C3N4, CN) has emerged as a promising photocatalytic material due to its inherent stability, antibacterial properties, and eco-friendliness. However, tendency aggregate limited dispersion hinder efficacy in practical applications. To address these limitations, this study focuses on developing composite hydrogel coating, which sodium alginate (SA) molecules interact electrostatically through hydrogen bonding anchor CN, thereby significantly improving dispersion. The optimal CN loading of 35% results with tensile strength 120 MPa an rate 99.87% within 6 h. enhanced mechanical properties are attributed between the -NH2 groups -OH SA, while SA facilitate attraction photogenerated holes from promoting carrier transfer separation, strengthening action. Moreover, coating exhibits excellent corrosion resistance capabilities against Pseudomonas aeruginosa 316L stainless steel (316L SS), laying foundation for advanced antimicrobial anticorrosion systems.

Titanium dioxide (TiO2), recognized for its affordability, low cost, high chemical stability, and eco-friendliness, has garnered extensive research attention in recent years. But because of the TiO2 band gap (>3.2eV) seriously limit use visible light, fast electron-hole composite often lead to poor photocatalytic activity quantum yield. Therefore, needs be modified. Modification can change broadband TiO2, enhance light absorption, thus affect important means efficiency. In this review, we introduce crystal form mechanism review some modification strategies including doping modification, construction heterojunctions, plane engineering defect engineering. Furthermore, application modified TiO2-based materials water treatment, removal dye contaminants, antibiotics, advanced oxidative sterilization, finally explore challenges prospects photocatalysts.

Photocatalysts, known their efficiency, broad-spectrum activity, environmental benefits, present a promising alternative. With development natural solar light driven photocatalysts, bactericidal range has been further extended. materials can be activated by various wavelengths to generate reactive oxygen species (ROS), which effectively eliminate wide pathogenic microorganisms including bacteria, fungi, protozoa. However, limited optical response range, suboptimal bandgap, slow electron cycling limit efficient generation ROS, resulting in lower sterilization efficiency photocatalytic antimicrobials. Additionally, short half-life migration distance restrict activity. This review focuses on process mechanism reactions, highlighting recent advances typical photocatalysts. We also explore strategies enhance diffusion utilization, morphology control, noble metal deposition, doping, co-catalyst loading, vacancy introduction, surface functionalization, heterojunction construction. These aim increase prolong thereby enhancing overall effectiveness. Thereafter, presents state-of-the-art applications photocatalysts water purification, medical coatings, air disinfection. Furthermore, it explores key challenges opportunities that may drive future innovations advancements applications, aiming develop more sustainable solutions.
