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

 

 

 

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 scanning
tunneling microscopy, surface x-ray scattering and x-ray
absorption spectroscopy.
