Platinum Surface Electrochemistry

The single crystal of platinum gently hangs atop an electrolyte surface. Electrochemistry is a surface-sensitive field of research, as the composition and atomic arrangement of the electrode drastically affect its properties. Atoms in a single crystal are highly ordered, and we are able to cut and polish a crystal in such a way that we only expose one of the many possible surface arrangements. The single crystal electrode is balanced on the surface of the electrolyte to ensure that only the polished surface is exposed. These experiments give us fundamental information about electrochemical reactions, which are integral to the field of clean energy.
