Abstract

The green synthesis of zinc oxide nanoparticles from plant extract is attracting great interest owing to the cost effectiveness and ecofriendly method of synthesis. Crystalline hexagonal shape zinc oxide (ZnO) nanoparticles of approximately 50-100 nm were synthesized through a one-step solution-based technique using alcohol free Artemisia pallens plant extract as a reducing agent. Analysis of the synthesized nanoparticles using X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) exhibited homogenous wurtzite structure. TEM and selected area electron diffraction studies showed the zinc oxide nanoparticles are crystalline and hexagonal with growth direction in (101) plane. Fourier transform infrared spectrum showed a single band at 478.34 cm−1 which can be attributed to Zn-O vibrational band. The composition of the synthesized ZnO nanoparticles was then confirmed through energy dispersive X-ray spectroscopy results. In this work, the antimicrobial activity of ZnO nanoparticles was studied. The development of synthesizing metal nanoparticles (MNPs) by plant extracts has become a major focus of research as these nanoparticles have low environmental hazards and low human toxicity. This makes it a commonly used source of nanoparticle synthesis with an efficient, extremely eclectic, relatively cheap and traditional agent that has been used for many years to successfully prepare different organic molecules and compounds.

青蒿植物提取物的氧化锌纳米颗粒的绿色合成、表征和抗菌活性

摘要

由于成本效益和环境友好的合成方法,从植物提取物中绿色合成氧化锌纳米颗粒引起了极大的兴趣。大约 50-100 nm 的晶体六边形氧化锌 (ZnO) 纳米颗粒是通过一步基于溶液的技术合成的,使用无酒精的属植物提取物作为还原剂。使用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和透射电子显微镜 (TEM) 分析合成的纳米颗粒,显示出均质的纤锌矿结构。TEM 和选区电子衍射研究表明氧化锌纳米颗粒是晶体和六边形,生长方向在(101)面。傅里叶变换红外光谱在 478.34 cm -1处显示单波段这可以归因于Zn-O振动带。然后通过能量色散 X 射线光谱结果确认合成的 ZnO 纳米粒子的组成。在这项工作中,研究了 ZnO 纳米颗粒的抗菌活性。通过植物提取物合成金属纳米粒子 (MNP) 的开发已成为研究的主要焦点,因为这些纳米粒子具有低环境危害和低人类毒性。这使其成为纳米粒子合成的常用来源,具有高效、极其折衷、相对便宜和传统的试剂,多年来已成功制备不同的有机分子和化合物。
