摘要: Heterostructured Co–Au core–shell nanoparticles have been synthesized by reducing AuCl4− ions on cobalt after a minor but effective modification of surface an amine. The core shell morphology is emphatically confirmed thorough investigation through UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), and transmission electron microscopic analysis (TEM). chemical composition topography were determined using STEM-HAADF EFTEM imaging. Fourier transform infrared (FTIR) confirms the Co interactions involved between ligands metals at various steps synthetic process. magnetic properties confirm material to be superparamagnetic in nature.
