Abstract

Abstract In recent years, nanoparticles have emerged as an important player in a broad range of applications, especially thanks to recent advances in their synthesis. The silver and copper nanoparticles are often used due to their antibacterial and fungicidal activities, and this article presents the results of the nanoparticle synthesis using electrical glow discharge generated directly in a volume of their salt solutions. Therefore, there is no influence of air (i.e. reactive nitrogen species) as it is usual in other commonly used approaches. Nanoparticles were prepared under various experimental conditions, and they were characterized by ultraviolet/visible spectrometry, dynamic light scattering, X-ray photoelectron spectroscopy, and high-resolution scanning electron microscopy. Particles were produced without any surfactant or stabilizing agent, and some of them showed higher resistance against agglomeration during their short-term (days) storage. The nanoparticle formation mechanism was confirmed by the fast camera imaging. Thus, the developed approach can be applied for simple environmentally friendly nanoparticle production for various applications.
在无机盐溶液中等离子体放电合成银和铜纳米粒子
摘要近年来,纳米颗粒在广泛的应用中发挥了重要作用,特别是由于其合成的最新进展。银和铜纳米颗粒由于其抗菌和杀菌活性而经常被使用,本文介绍了使用在一定体积的盐溶液中直接产生的辉光放电合成纳米颗粒的结果。因此,没有空气(即活性氮物种)的影响,这在其他常用方法中是常见的。在不同的实验条件下制备了纳米颗粒,并通过紫外/可见光谱、动态光散射、X射线光电子能谱和高分辨率扫描电子显微镜对其进行了表征。颗粒是在没有任何表面活性剂或稳定剂的情况下生产的,其中一些颗粒在短期(几天)储存期间表现出更高的抗结块性。通过快速相机成像证实了纳米颗粒的形成机制。因此,所开发的方法可以应用于各种应用的简单环保纳米颗粒生产。
