2. Pt submonolayer on Ru (PtRu20) Electrocatalysts: H2, CO and reformate H2 oxidation; Pt content is 1/10 of that in commercial catalysts, high CO tolerance; Oxidation of Methanol and Ethanol; Adsorbate-Surface Interactions. Pt submonolayer anode electrocatalyst
The first Pt monolayer-level electrocatalyst
No change in performance during ca. 900
hours as anode under fuel cell operating conditions
Research Activities: Surface Electrochemistry
To obtain a true microscopic description of electrochemical interfaces,
structural and electronic properties of atomic and molecular monolayers on
single-crystal and nanoparticle substrates are investigated using in situ
tunneling microscopy, surface x-ray scattering and x-ray
