Coadsorption of anions and ultra-thin metal films on single crystal electrodes
… metallic films of copper and silver deposited on single crystal electrodes. The anion and metal coverages from the Auger electron spectroscopy (AES) measurements were compared with results obtained by in situ radiochemical and electrochemical data. Using Low Energy Electron Diffraction (LEED), the …

Adsorption of Anions on Platinum and Rhodium Single-Crystal Electrodes: Ultrahigh Vacuum Approach
… anion-like urea molecule on platinum and rhodium single crystal electrodes. It reports on the composition and structure of bisulfate and urea on Pt(111) and Pt(100) surfaces and on the reactivity of perchlorate on Rh(100), Rh(111) and Rh(poly) electrodes. The composition and structure of chloride …

A radiotracer technique for in situ adsorbate measurements on smooth electrode surfaces
… measuring in situ adsorption onto smooth metal electrodes has been developed. In this method, a radiolabeled adsorbate on an electrode is detected by pressing the electrode against a glass scintillator detector at the bottom of an electrochemical cell. Equations which account for the …
