The use of the green synthesis method helps to reduce the toxicity of nanomaterials both when they are obtained and when they are used in various areas. Therefore, in recent years, in order to ensure the sustainability of ecosystems, special attention has been paid to ecological approaches using simple and safe reaction conditions and harmless precursors. This article presents the results of SEM and XPS studies of nickel nanoparticles obtained by green synthesis using the extract of the Fumaria officinalis.
