제목 Anisotropic Growth of Triangular Gold Nanostructures for Plasmonic Photocatalysts
초록 Localized surface plasmon resonance (LSPR) of the metal nanocrystal, resulting from the light-to-matter interaction, is greatly considering as a key role in visible light photocatalysts. For the face-centered cubic (fcc) gold nanoparticle, the crystal facets are primarily dominated with the low surface energies such as {111} and {100}. Such gold nanoparticles are anticipated catalytically less active than other gold nanocrystals with higher surface energies. In this study, we show the crystal facet-dependent photocatalytic activity with anisotropic gold nanocrystals. We prepared anisotropic gold nanostructures through the seed-mediated method with similar size of gold nanoparticles. We carried out the photochemical reaction with synthesized gold nanostructures and compared it with gold nanoparticles. The synthesized gold nanostructures were characterized by XRD, TEM, and the photoreactivity was measured using UV-Vis spectrophotometer.
