Plasmonic photocatalyst : Anchoring the dye [Ru(bpy) 3 ] 2+ (bpy=2,2′‐bipyridine) on the surface of Ag nanoparticles coated with a thin SiO 2 layer (see picture) afforded a photocatalyst whose phosphorescence emission and photoinduced oxidation activity in the selective liquid‐phase oxidation of styrene are efficiently enhanced through interaction with the localized surface plasmon resonance of the core Ag nanoparticles.
