Green Synthesis of Magnetic Fe–Co Bimetallic Nanoparticles and Their Photocatalytic Activity

Abstract

The leaves of the Murraya koenigii aromatic plant contain various specific phytochemicals, including lutein, β-carotene, vitamin C, nicotinic acids, and other polyphenols, which act as reducing agents to produce metallic nanoparticles from their respective precursors. In this study, we report the green synthesis of iron–cobalt bimetallic nanoparticles (Fe–Co BMNPs) using natural resources of reducing and capping agents from aqueous extract of Murraya koenigii leaves. The synthesized Fe–Co BMNPs were characterized using SEM, EDS, BET surface area, TGA, XRD, TEM, and VSM techniques, revealing their crystalline structure with a surface area of 83.22 m2 g−1 and particle sizes 97% of 10 mg L−1).
