ABSTRACT: Noble metal Ag nanoparticles with unique surface plasmon resonance property have attracted much attention recently in the field of photocatalysis. Based on the advantages of Ag nanoparticles and semiconductor CeO2, a novel plasmonic photocatalyst Ag-AgCl/CeO2 was prepared with a facile route. The as-prepared samples were characterized using scanning and transmission electron microscopy, X-ray photoelectron spectroscopy and UV-vis diffusion re?ection spectroscopy. This metal-semiconductor nanocomposite plasmonic photocatalyst exhibited a high visible-light photocatalytic activity and good stability for photocatalytic degradation of methyl orange in water. Ag-AgCl/CeO2 will be a potentially promising plasmonic photocatalysts for organic pollutant degradation and water purification.
