Synthesis of nanoparticles (NPs) for many different uses requires the development of environmentally friendly synthesis protocols. In this article, we present a simple and environmentally friendly method to synthesize lead oxide (PbO) NPs from the plant material of the . Analytical techniques such as spectroscopy, X-ray diffraction, and microscopy were used to characterize the synthesized PbO NPs, and their photo-electrocatalytic and antifungal properties were also evaluated. HO was used to investigate the efficacy of removing methylene blue dye. At a range of pH values, HO was used to study the role of hydroxyl radicals in the breakdown of methylene blue dye. Methylene blue dyes are more easily eliminated due to increased generation of the *OH radical during removal. Dye degradation was also significantly affected by the aqueous medium's pH. Additionally, the electrocatalytic properties of the PbO NPs adapted electrode were studied in CHCOONa aqueous solution using cyclic voltammetry. Excellent electrocatalytic properties of the PbO NPs are shown by the unity of the anodic and cathodic peaks of the modified electrode in comparison to the stranded electrode. , , and were some fungi tested with the PbO NPs. (40%) and (50%), and (75%), the PbO NPs display an excellent inhibition zone. Finally, PbO NPs were used in antioxidant studies with the powerful antioxidant 2, 2 diphenyl-1-picrylhydrazyl (DPPH). This study presents a simple and environmentally friendly method for synthesizing PbO NPs with multiple uses, including photo-electrocatalytic and antimicrobial activity.
合成用于多种不同用途的纳米颗粒（NPs）需要开发环境友好的合成方案。在本文中，我们提出了一种简单且环境友好的方法，从[植物名称]的植物材料中合成氧化铅（PbO）纳米颗粒。使用光谱学、X射线衍射和显微镜等分析技术对合成的PbO纳米颗粒进行表征，并评估了它们的光电催化和抗真菌性能。使用羟基自由基（HO）来研究去除亚甲基蓝染料的效果。在一系列pH值下，使用HO来研究羟基自由基在亚甲基蓝染料分解中的作用。由于在去除过程中*OH自由基的生成增加，亚甲基蓝染料更容易被去除。染料降解也受到水介质pH值的显著影响。此外，使用循环伏安法在CH₃COONa水溶液中研究了PbO纳米颗粒修饰电极的电催化性能。与裸电极相比，修饰电极的阳极和阴极峰的一致性表明PbO纳米颗粒具有优异的电催化性能。[真菌名称1]、[真菌名称2]和[真菌名称3]是用PbO纳米颗粒测试的一些真菌。对于[真菌名称1]（40%）、[真菌名称2]（50%）和[真菌名称3]（75%），PbO纳米颗粒显示出优异的抑菌圈。最后，PbO纳米颗粒与强大的抗氧化剂2,2-二苯基-1-苦基肼（DPPH）一起用于抗氧化研究。本研究提出了一种简单且环境友好的方法来合成具有多种用途的PbO纳米颗粒，包括光电催化和抗菌活性。
