“…These signals represent the (111), (200), (220), and (311) reflection plane of the silver nanoparticles. 42 During the formation of the IO/Ag nanocomposite particles, silver might be deposited on the surface of the iron oxide particles. For this reason, in the XRD pattern of the IO/Ag nanocomposite particles, the diffraction signals due to iron oxide seed particles almost disappeared.…”
