Palladium is widely used in various chemical reactions due to its high catalytic activity characteristics. Although metal nanoparticles have attracted much interest in photocatalytic reactions, palladium exhibits lower plasmonic properties than coinage metals such as Au, Ag, and Cu. We developed Au/Pd bimetallic core-shell structure for a highly efficient plasmon-mediated photocatalyst. After the Au/Pd nanostructures were synthesized with controlling the thickness of the Pd shell, they were used as photocatalysts for reducing 4-Nitrothiophenol to 4-Aminobenzenethiol, which were observed by in-situ Raman Spectroscopy. We demonstrated a synergistic effect of Au/Pd nanostructures combining the inherent catalytic effect of palladium with the plasmonic effect of Au nanoparticles.
