Abstract

Abstract The design of chemical processes and products with a low use of hazardous substances is known as “green chemistry.” The method of producing nanoparticles (NPs) significantly affects their size and characteristics. Currently, there are two primary methods utilized for synthesizing NPs, known as the bottom-up and top-down approaches. To keep the prices of nanotechnology-based products, the green method employs plant metabolites as reducing agents. Two types of magnetite NPs (Fe3O4 NPs) were synthetized and characterized being denominated NPs1 synthetized by the co-precipitation method and NPs2 synthetized using the green synthesis process. It was found that the Fe3O4 NPs1 has a quasi-spherical morphology with a size of 43 nm, while the Fe3O4 NPs2 has a size of 6 nm.
