Fabrication of silver nanoparticles loaded flowerlike CeF3 architectures and their antibacterial activity

Publication date: September 2018 Source:Journal of Physics and Chemistry of Solids, Volume 120 Author(s): Lijuan Wang, Weirui Zhang, Yanbao Zhao, Liuqin Cao Cerium fluoride (CeF3) architectures with size of 200–300 nm were prepared by hydrothermal method. Their morphology and property were investigated by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), zeta potentials and Fourier transform infrared (FT-IR) spectrometry. The prepared CeF3 architectures present flower-like shape and consist of nanosheets. Their dispersion stability was improved by modification with chitosan/carboxymethyl chitosan (CTS/CMCTS). After modification, silver nanoparticles (Ag NPs) were successfully loaded on the surface of CeF3 architectures via in situ growth. As novel antibacterial materials, both CeF3/CTS/Ag and CeF3/CMCTS/Ag exhibit good antibacterial activities against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) due to the synergistic effect of CeF3 and silver nanoparticles.
