제목 Broadband Absorption from PES/Au composite in Heterogenous Catalysis
초록 Localized Surface Plasmon Resonance (LSPR) known to be able in catalyzing various chemical reaction systems owing to the near-electromagnetic field, hot electron transfer and photothermal heating. As it is known that plasmonic interparticle coupling can increase the amplitude of the LSPR activities, superstructure consisted of multiple layers of plasmonic nanoparticles are suggested to increase the performance of LSPR-mediated catalytic reaction. In accordance with this, we prepare a layer-by-layer (LbL) assembly of Au NPs and polyelectrolytes onto a porous polyethersulfone (PES) membrane. In the LbL assembled membrane, an extensive plasmonic coupling among Au NPs causing the broadband absorption of the plasmonics NPs. By illuminating the prepared PES/Au composites by artificial sun light, the LSPR effect on a model chemical reaction is being investigated by comparing the spectral overlap between illuminated light and the plasmonic absorption of PES/Au composites.
