Abstract

Water pollution by synthetic dyes and pathogens poses severe environmental and health risks. This study offers a green solution by biosynthesizing zinc oxide (ZnO) and selenium-doped ZnO (Se@ZnO) nanoparticles using Ficus religiosa (FR) extract as a reducing and stabilizing agent. Structural and optical analyses (XRD, FTIR, FESEM-EDX, UV–Vis, PL, BET, XPS) confirmed crystalline structures and morphological transformation from nanorods (ZnO) to nanoflakes (FRSe@ZnO). The FRSe@ZnO showed a reduced bandgap (2.70 eV) and increased surface area (121 m²/g). Photocatalytic studies revealed that FRSe@ZnO achieved 99 % degradation of fast green dye in 100 min under visible light, outperforming ZnO (79 %) and Se@ZnO (91 %). It also exhibited good recyclability, pH-responsive behavior, and ROS scavenging activity. Moreover, FRSe@ZnO demonstrated significant antimicrobial effects against various pathogens, as well as antidiabetic and anti-inflammatory potential. These findings highlight the promise of green-synthesized, multifunctional nanomaterials for sustainable environmental cleanup and biomedical applications.

Green利用榕叶提取物合成Se@ZnO纳米复合材料，增强了快速绿色染料的光催化降解和生物应用

由合成染料和病原体造成的水污染构成了严重的环境和健康风险。本研究提出了一种绿色解决方案，即利用榕叶（FR）提取物作为还原剂和稳定剂，生物合成氧化锌（ZnO）和硒掺杂氧化锌（Se@ZnO）纳米颗粒。结构和光学分析（XRD， FTIR, FESEM-EDX, UV-Vis， PL， BET， XPS）证实了晶体结构和从纳米棒（ZnO）到纳米片的形态转变（FRSe@ZnO）。FRSe@ZnO的带隙减小（2.70 eV），比表面积增大（121 m2/g）。光催化研究表明，FRSe@ZnO在可见光下100分钟内对快速绿色染料的降解率达到99%，优于ZnO（79%）和Se@ZnO（91%）。它还具有良好的可回收性、ph响应行为和活性氧清除活性。此外，FRSe@ZnO显示出对各种病原体的显著抗菌作用，以及抗糖尿病和抗炎潜力。这些发现突出了绿色合成的多功能纳米材料在可持续环境清理和生物医学应用方面的前景。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
