Enhancement of Scattering and Near Field of TiO2-Au Nanohybrids Using a Silver Resonator for Efficient Plasmonic Photocatalysis

Maosong Liu et al.

Summary: The recent application of localized surface plasmon resonances (SPRs) in metallic nanoparticles has led to the construction of plasmonic nanohybrids for heterogeneous photocatalysis. By encapsulating an Ag NP core with SiO2 and TiO2 layers, and Au NPs on the outer surface, an efficient plasmonic photocatalyst, Ag@SiO2@TiO2-Au, has been designed to enhance catalytic activity. The structure unit with strong scattering and field enhancement induced by a plasmonic resonator is shown to significantly boost photocatalytic activity for high H-2 production rates under visible light.
