摘要：I will present our recent research on the use of ultramicroelectrodes (UMEs) to study single electrocatalytic nanoparticles. My group has been studying stochastic electrochemical events of single metal nanoparticles at UME surfaces in order to better understand interfacial electron-transfer processes and structure-function of nanocatalysts. One of our approaches uses fast-scan cyclic voltammetry (FSCV) to record voltammetric response of single nanoparticles during collision. FSCV gives unique kinetic information and chemical resolution. Amperometric recording allows one to record single collision events with microsecond temporal resolution. We have discovered some exciting details in collision studies using fast recording speed. I will also describe our most recent experiments in which single metal nanoparticles are oxidized and dissolved at the electrode surface leading to unique oxidation behavior which has never been seen before.??
