摘要: A plasmonic photocatalyst of Ag/AgCl@TiO2 nanoparticles (NPs) was directly prepared by a one-step sonochemical method. Both Ag NPs and AgCl were co-deposited on TiO2 to form Ag@TiO2 using the Due localized surface effects NPs, visible-light absorbance dramatically increased photocatalytic activity decompose Rhodamine B much improved under visible light. In addition, due advantages approach, only very small amount is required obtain high in catalyst. The mechanism for enhancement visible-light-driven activities also analyzed.
