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.
