Pt-Ru fuel cell catalysts subjected to H2, CO, N2 and air atmosphere: An X-ray absorption study
- Applied Catalysis A: General, 319, p.81-90, 2007 .
In situ X-ray absorption spectroscopy (XAS)measurements were carried out on commercial carbon-supported Pt, Ru and Pt-Ru alloy electrocatalysts as well as a Pt/Ru mixture electrocatalyst in a specifically designed reactor/furnace set-up at the Pt L3 and the Ru K edge. The catalysts were heated to 100 8C and subjected to different atmospheres - 5
