The constricted visible light harvesting and undesirable rapid recombination of photogenerated e^- and h⁺ set enormously hinder the activity of the photocatalysts. In this work, we design and develop two-dimensional/one-dimensional (2D/1D) S-g-C₃N₄/Co-NiS heterojunction with intimate heterointerface contact by self-assembly technique. The fast electron transportation of 2D S-g-C₃N₄ nanosheets (NSs) and the well-matched energy levels of bare S-g-C₃N₄ and 5% Co-NiS nanorods (NRs) cooperative support the transportation and separation of photo-carriers at the heterointerface of S-g-C₃N₄/Co-NiS. The as-fabricated samples were evaluated EDX, SEM, UV–vis, XRD, TEM, FTIR, XPS, BET, PL and transient photocurrent. Moreover, this well-defined construction boosts sunlight harvesting and exhibits a large surface area. Benefiting from the intimate coupling and structural features, the 20% S-g-C₃N₄/Co-NiS heterojunction attains a noteworthy photocatalytic methylene blue (MB) degradation rate of 100%, considerably improved than that of bare NiS (34%), 5% Co-NiS (57%) and pristine S-g-C₃N₄ (31%). Concurrently, the photocorrosion of bare S-g-C₃N₄ was suppressed by simultaneous integrating with NiS and engineering with cobalt, which was demonstrated through a chemical stability test with 6 consecutive experimental tests. Such outstanding enrichment in photocatalytic activity and chemical stability was primarily attributed to boosting spatial charge separation and synergistic effects of the 20% 2D/1D S-g-C₃N₄/Co-NiS nanocomposites (NCs). Antibacterial performance of 20% 2D/1D S-g-C₃N₄/Co-NiSNCs against 4 infectious species was evaluated in visible light radiance. Our results emphasize the great importance of the efficacious heterointerface blend of 2D/1D S-g-C₃N₄/Co-NiS NCs as a promising photocatalyst scheme for enhanced photocatalytic degradation of dye and disinfection of pathogens.

受限制的可见光捕获和光生 e ^-和 h ^{+ 的}不希望的快速重组极大地阻碍了光催化剂的活性。在这项工作中，我们通过自组装技术设计和开发了具有紧密异质界面接触的二维/一维 (2D/1D) SgC ₃ N ₄ /Co-NiS 异质结。二维 SgC ₃ N ₄纳米片 (NSs)的快速电子传输和裸 SgC ₃ N ₄和 5% Co-NiS 纳米棒 (NRs)的良好匹配能级协同支持异质界面处光载流子的传输和分离SgC ₃ N ₄/Co-NiS。对制造的样品进行了 EDX、SEM、UV-vis、XRD、TEM、FTIR、XPS、BET、PL 和瞬态光电流的评估。此外，这种明确定义的结构促进了阳光收集并展示了大的表面积。受益于紧密耦合和结构特征，20% SgC ₃ N ₄ /Co-NiS 异质结实现了 100% 的显着光催化亚甲蓝 (MB) 降解率，比裸 NiS (34%) 显着提高了 5% Co-NiS (57%) 和原始 SgC ₃ N ₄ (31%)。同时，裸SgC ₃ N ₄的光腐蚀通过与 NiS 的同时集成和与钴的工程化来抑制，这通过具有 6 个连续实验测试的化学稳定性测试得到了证明。光催化活性和化学稳定性的这种显着富集主要归因于 20% 2D/1D SgC ₃ N ₄ /Co-NiS 纳米复合材料 (NCs) 的空间电荷分离和协同效应。在可见光辐射下评估了 20% 2D/1D SgC ₃ N ₄ /Co-NiSNCs 对 4 种传染性物种的抗菌性能。我们的结果强调了有效的 2D/1D SgC ₃ N ₄异质界面混合物的重要性/Co-NiS NCs 作为一种有前途的光催化剂方案，用于增强染料的光催化降解和病原体的消毒。
