Surface-Enhanced Raman Scattering Study of the Product-Selectivity of Plasmon-Driven Reactions of p‑Nitrothiophenol in Silver Nanowires.

ABSTRACT: Nanoplasmonic photocatalysis shows a huge potential for efficient light energy harvesting by leveraging the unique and peculiar properties of plasmonic metallic nanostructures (usually Ag or Au) to drive light-induced chemical reactions. Plasmonic catalysis of the coupling reaction of p-nitrothiophenol (PNTP) over silver nanowires (AgNWs) and -quasi-spherical silver nanoparticles (AgNPs) has been intensively investigated by in situ surface-enhanced Raman scattering (SERS). The reduction of PNTP is often used as a model system in plasmonic photocatalysis basic science since the conversion of the nitro group into an amino (p-aminothiophenol, PATP) or an azo (4,4'-dimercaptoazobenzene, DMAB) group is a well-documented reaction that can occur through a wide variety of chemical pr
