Abstract: In the present work, a hybrid Ag@CeO₂ nanostructure composite was synthesized via a facile oxidation redox coating approach. The characterization by X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy indicates Ag nanoparticles (NPs) are firmly attached to the surface of the CeO₂ nanoparticles, driven by the strong interfacial interaction between Ag NPs and CeO₂. The antibacterial effects of the Ag@CeO₂ hybrid nanocomposite against prokaryotic bacteria were tested using disk diffusion and turbidity method. The plausible mechanism was proposed for the inhibition of bacterial growth.
