title = "An electrochemical STM study of coarsening and corrosion of platinum films",
abstract = "In-situ electrochemical scanning tunneling microscopy is used to study the coarsening of platinum crystals under potentiostating and the dissolution and coarsening of platinum crystals through potential cycling. A rapid coarsening of platinum crystals was observed for potentiostating in the double-layer region. It is suggested that the coarsening is a variant of Ostwald ripening dominated by surface-diffusion transport. In addition, potential cycling not only causes surface platinum dissolution as a result of the platinum redox reaction but also platinum crystal ripening. Details of the platinum surface restructuring are described and the possible influences of these phenomena on fuel cell operation are discussed.",
