Abstract
Scanning tunneling microscopy (STM) was used to investigate the surfaces of Pt(111) single crystals interfaced with YSZ and β″-Al2O3 at atmospheric pressure. In both cases the STM imaged the reversible electrochemically controlled dosing (backspillover) of O2− species and of Na+ species on Pt(111) surface respectively, which both form a (12 × 12) hexagonal structure on the Pt(111) surface. On the mechanistic side, the STM has confirmed the backspillover mechanism of electrochemical promotion and metal support interactions.
