The work aimed to synthesize three heterojunction photocatalysts (E_g = 2.65 to 2.78 eV) via in-situ encapsulation of 5% zinc doped titanium oxynitride (Zn_0.05TiO_xN_y) catalyst into MOF-5 and bulk (BCN)/ sulfur-doped (SCN) g-C₃N₄ supports using a microwave method. The prepared photocatalysts were characterized and utilized to purify textile industrial wastewater from the organic dye (e.g., methylene blue, MB) and microbial (e.g., E. coli, S. aureus, and C. albicans) contaminants under dark, visible, and solar lights. The output data confirmed the higher activity of Zn_0.05TiO_xN_y@SCN and Zn_0.05TiO_xN_y@MOF-5 for photo-induced microbial growth inactivation (> 90%) under visible light, with photo-biocidal efficiency of 0.91 to 1.69 mCFU/Einstein. Such a phenomenon is ascribed to the synergism between the high antimicrobial capacity of supports and photoactivity of Zn_0.05TiO_xN_y. Also, Zn_0.05TiO_xN_y@SCN exhibited far superiority to mineralize MB dye ($K_{\mathit{photo}}$ of 2.73 × 10^-2 min^-1) under direct sunlight, as confirmed by GC-MS analysis, due to its high photonic (ζ% of 4.4 – 8.3%)/quantum (QE of 0.56 – 0.54%) efficiencies for the generation of hydroxyl and superoxide (^-•O₂/•OH) oxidative species. As a practical case study, all heterojunction photocatalysts also demonstrated high-performance stability (5 cycles) for real textile wastewater treatment under sunlight (efficiency = 76.1 - 84.6%).

该工作旨在通过将5％掺锌的氮氧化钛（Zn _0.05 TiO _x N _y）催化剂原位封装到MOF-5和本体（BCN）/硫-中来合成三种异质结光催化剂（E _g = 2.65至2.78 eV）。用微波方法掺杂的（SCN）gC ₃ N ₄载体。表征了所制备的光催化剂，并将其用于在黑暗，可见光和日光下从有机染料（例如亚甲基蓝，MB）和微生物（例如大肠杆菌，金黄色葡萄球菌和白色念珠菌）污染物中纯化纺织工业废水。灯。输出数据证实了Zn _0.05 TiO具有更高的活性_x N _y @SCN和Zn _0.05 TiO _x N _y @ MOF-5用于可见光下的光致微生物生长失活（> 90％），光杀菌效率为0.91至1.69 mCFU /爱因斯坦。这种现象归因于载体的高抗菌能力与Zn _0.05 TiO _x N _y的光活性之间的协同作用。同样，Zn _0.05 TiO _x N _y @SCN表现出远远优于矿化MB染料（${ķ}_{\mathit{照片}}$GC-MS分析证实，在阳光直射下的光通量为2.73×10 ^-2  min ^-1），这是因为其光子产生效率高（ζ％为4.4 – 8.3％）/量子效率（QE为0.56 – 0.54％）羟基和超氧化物（^-• O ₂ /•OH）的氧化性。作为一个实际案例研究，所有异质结光催化剂还表现出了在阳光下实际纺织废水处理中的高性能稳定性（5个循环）（效率= 76.1-84.6％）。
