In-situ STM characterisation of the surface morphology of platinum single crystal electrodes as a function of their preparation
A systematic study of the surface morphology of Pt (111) and Pt (100) electrodes as
prepared by flame-annealing and cooling in different atmospheres (air, N2, H2+ N2 and
CO+ N2) is presented. The electrodes were characterised by cyclic voltammetry and in-situ
STM in 0.1 M H2SO4. Preliminary voltammetric results for Pt (110) are also shown. In this
case, Cu upd served as a structure sensitive probe. It was observed that the presence of
oxygen during cooling induces surface defects and leads to rough surfaces. Cooling in pure …
