Plasmonic nanoparticles have been of particular interest due to their characteristic and controllable optical properties that can be useful for various optical signal enhancements and photocatalytic reactions. Plasmonic behavior originates from the collective oscillation of free electrons in plasmonic materials. We monitored and analyzed the plasmonic behavior in photocatalytic reaction and electrochromic behavior using electrochemical measurements. We demonstrated a plasmon-enhanced catalytic reaction with Pd/Au bimetallic structure and observed electrochromic behaviors of Au nanocubes with varying electrical potential, which was monitored by in-situ dark-field microscopy.
