Abstract
Ethylene adsorbed on the stoichiometric RuO2(110) surface at 85 K is investigated applying high resolution electron energy loss spectroscopy and thermal desorption spectroscopy in combination with isotope labeling experiments. Under the applied conditions (ultra high vacuum, no continuous reactant supply) ethylene does not react with stoichiometric RuO2(110) and is desorbed molecularly at 320 K. Warming to 260 K leads to a rearrangement of C2H4 from pi- to sigma-bonded.
