Effect of core@shell (Au@Ag) nanostructure on surface plasmon-induced photocatalytic activity under visible light irradiation

We prepared Au-Ag nanoparticles (NPs) with two different morphologies over SrTiO3 to investigate the effect of composite nanostructure on surface plasmon-induced photocatalytic activity; [email protected] ([email protected]) NPs were synthesized by a multi-step citric reduction method, and Au-Ag bimetallic NPs were prepared by a photo-reduction method. ([email protected])/SrTiO3 and Au-Ag/SrTiO3 showed strong photoabsorption in the visible light...
