Researchers aim to develop photoactive systems to address critical environmental challenges, presenting a significant ongoing challenge. This study emphasizes the construction of pure metal oxide NPs (ZnO, MnO, and SnO), tellurium-doped metal oxides, and composite materials of graphitic carbon nitride/tellurium-doped metal oxides to enhance photocatalytic performance in methylene blue (MB) degradation under natural sunlight. Various characterization techniques, XRD, EDX, SEM, FTIR and UV–Vis Spectroscopy, were employed to analyze the structure, shape, and optical features of the materials. The photocatalytic degradation order for MB was determined to be pure and doped ZnO > pure & doped SnO > pure & doped MnO. ZnO NPs exhibited the highest photocatalytic degradation at 98 %, accredited to their higher crystallinity, insignificant surface area and reduced particle dimension. Pure and doped ZnO NPs demonstrated the maximum zone of inhibition, reaching 39.5 mm. Consequently, S-g-CN/Te-ZnO emerges as the most promising material, serving as both a photocatalytic and antibacterial agent.

揭示环境解决方案的未来：Sg-C3N4/Te 掺杂金属氧化物（ZnO、Mn3O4 和 SnO2）作为光催化和抗菌技术的游戏规则改变者

研究人员的目标是开发光敏系统来应对关键的环境挑战，这是一个重大的持续挑战。本研究重点构建纯金属氧化物纳米粒子（ZnO、MnO 和 SnO）、碲掺杂金属氧化物以及石墨碳氮化物/碲掺杂金属氧化物复合材料，以增强亚甲基蓝（MB）降解中的光催化性能。自然阳光。采用 XRD、EDX、SEM、FTIR 和紫外可见光谱等各种表征技术来分析材料的结构、形状和光学特征。MB的光催化降解顺序为纯和掺杂ZnO>纯和掺杂SnO>纯和掺杂MnO。ZnO NPs 表现出最高的光催化降解率，达到 98%，这归因于其较高的结晶度、较小的表面积和较小的颗粒尺寸。纯的和掺杂的 ZnO NPs 表现出最大抑制区，达到 39.5 mm。因此，Sg-CN/Te-ZnO 成为最有前途的材料，可用作光催化剂和抗菌剂。
