- •
Adsorption and reaction of ethylene, C2H4, on Ru(0001) were studied with RAIRS.
- •
Ethylene adsorbs without dissociation at 95 K as a di-σ-bonded species.
- •
At 150 K, C2H4 begins to convert to ethylidyne (CCH3), which is stable up to 320 K.
- •
Above 320 K, ethylidyne dehydrogenates to ethynyl (CCH), which is stable to 420 K.
- •
Above 450 K, ethynyl dissociates to form methylidyne, CH, on the surface.
