From ultra-high vacuum to the electrochemical interface: X-ray scattering studies of model electrocatalysts
Abstract
In-situ surface X-ray scattering (SXS) has become a powerful probe of the atomic structure at the metal–electrolyte interface. In this paper we describe an experiment in which a Pt(111) sample is prepared under ultra-high vacuum (UHV) conditions to have a p(2 × 2) oxygen layer adsorbed on the surface. The surface is then studied using SXS under UHV conditions before successive transfer to a bulk water environment and then to the electrochemical environment (0.1 M
