Nanoparticle-electrode collision processes: The underpotential deposition of thallium on silver nanoparticles in aqueous solution

The electrochemistry of collisions between metal nanoparticles (NPs) and electrode surfaces has been of recent interest with the development of anodic particle coulometry as a characterisation method. For the first time the underpotential deposition of metal ions from solution onto metal nanoparticles during collisions between the NPs and an inert electrode is reported (see picture).
