Observing electrochemistry on single plasmonic nanoparticles

Noble metal nanoparticles with plasmon resonance features have been widely applied in electrocatalysis and photo-electrochemistry owing to their unique physical, optical, catalytic properties. As heterogeneity of nanostructures has considerable influence on activities, investigation electrochemical process a single nano-catalyst is necessary eliminate bulk effect averaged results. Dark-field microscopy (DFM) enables the measurements scattering spectroscopy nanoparticle. Integrating electrochemistry, DFM provides powerful tool real-time monitor reactions at nanoscale surface get new insight into reaction mechanism. Herein, this mini-review presented impressive applications single-nanoparticle electrochemistry discussed recent progress its performance enhanced sensitivity resolution.
