Kaolin-based graphitic carbon nitride (g-CNx) composite photocatalysts were synthesized from a urea precursor using commercial kaolin. Structural characterization by X-ray diffraction and infrared spectroscopy (FTIR) verified the successful thermal polycondensation of g-CNx along dehydroxylation kaolinite to metakaolin at 550 °C. The content composites estimated thermogravimetry CHN analysis, ranging ca. 87 m/m% 2 dry mass. addition kaolin during synthesis was found have significant effect: yield in situ formed drastically decreased (from 4.9 3.8–0.1 m/m%) with increasing content. FTIR indicated presence nitrogen-rich g-CNx, having specific surface area 50 m2/g, which synergistically increased after 67–82 m2/g. Estimated optical band gaps affinity absorb visible light spectrum (λ < 413 nm). Photocatalytic activity upon both UV artificial sunlight irradiation observed hydroxyl radical evolution, however, without synergistic effect expected favorable porosity.

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.
