| Abstract: | Mesoporous CeO2 with high specific surface area was synthesized using a modified evaporation-induced self-assembly(EISA) method,and a series of different amounts of Ag were loaded to this mesoporous CeO2 by a modified ethylene glycol reduction route,The samples were characterized by powder X-ray diffraction(XRD),transmission electron microscopy(TEM),energy-dispersive spectrometry(EDS),nitrogen adsorption-desorption,Brunauer-Emmett-Teller(BET) and Barrett-Joyner-Halenda(BJH) methods,The mesoporous CeO2 structure with different proportions of silver nanoparticles and its antibacterial activity were adequately studied,confirming that obtained novel materials show a good antibacterial effect. |
