Abstract：
In the current investigation, zinc oxide (ZnO) nanoparticles and Fe-doped ZnO nanoparticles were sustainably synthesized utilizing an extract derived from theRumex dentatusplant through a green synthesis approach. The Scanning electron microscope (SEM), X-ray diffraction (XRD), Energy-dispersive x-ray spectroscopy (EDX), Ultra-violet visible spectroscopy (UV-vis) spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and Thermogravimetric analysis (TGA) techniques were used to examine the compositional, morphological, optical, and thermal properties of both samples. The doping of iron into ZnO NPs has significantly influenced their properties. The analysis firmly established that both ZnO NPs and Fe-doped ZnO NPs have hexagonal wurtzite structures and spherical shapes by XRD and SEM. The EDX analysis suggests that iron atoms have been successfully integrated into the ZnO lattice. The change in color observed during the reaction indicated the formation of nanoparticles. The UV-vis peaks at 364 nm and 314 nm confirmed the presence of ZnO NPs and Fe-doped ZnO NPs, respectively. The band gap of ZnO NPs by Fe dopant displayed a narrowing effect. This indicates that adding iron ions to ZnO NPs offers a control band gap. The thermal study TGA revealed that Fe-doped ZnO NPs remain stable when heated up to 600 °C. The antibacterial efficacy of ZnO NPs and Fe-doped ZnO NPs was evaluated against several bacterial strains. The evaluation is based on the zone of inhibition (ZOI). Both samples exhibited excellent antibacterial properties as compared to conventional pharmaceutical agents. These results suggest that synthesizing nanoparticles through plant-based methods is a promising approach to creating versatile and environmentally friendly biomedical products.
摘要：
在目前的调查中,通过绿色合成方法，利用源自Rumexdentatus植物的提取物可持续合成氧化锌（ZnO）纳米颗粒和Fe掺杂的ZnO纳米颗粒。扫描电子显微镜(SEM),X射线衍射(XRD)能量色散X射线光谱(EDX),紫外可见光谱(UV-vis)光谱,傅里叶变换红外光谱(FTIR),和热重分析(TGA)技术用于检查成分，形态学,光学，和两个样品的热性能。在ZnONPs中掺杂铁对其性能有很大影响。通过XRD和SEM分析确定ZnONPs和Fe掺杂的ZnONPs均具有六方纤锌矿结构和球形。EDX分析表明，铁原子已成功整合到ZnO晶格中。在反应期间观察到的颜色变化表明纳米颗粒的形成。364nm和314nm处的UV-vis峰证实了ZnONP和Fe掺杂的ZnONP的存在,分别。Fe掺杂的ZnONPs的带隙显示出变窄的效果。这表明将铁离子添加到ZnONP提供了控制带隙。热研究TGA表明，当加热到600°C时，Fe掺杂的ZnONPs保持稳定。评估了ZnONP和Fe掺杂的ZnONP对几种细菌菌株的抗菌功效。评价基于抑制区(ZOI)。与常规药剂相比,两种样品均表现出优异的抗菌性能。这些结果表明，通过基于植物的方法合成纳米颗粒是创造多功能和环境友好的生物医学产品的一种有前途的方法。
