Ethylene adsorption on regularly stepped copper surface: C2H4 on Cu(210)
Ethylene adsorption on regularly stepped Cu(210) surface was investigated with infrared reflection–adsorption spectroscopy and temperature programmed desorption. At 90 K, π-bonded ethylene was adsorbed on Cu(210) molecularly and all species were desorbed below 160 K. There were three types of π-bond...

| الملخص: | Ethylene adsorption on regularly stepped Cu(210) surface was investigated with infrared reflection–adsorption spectroscopy and temperature programmed desorption. At 90 K, π-bonded ethylene was adsorbed on Cu(210) molecularly and all species were desorbed below 160 K. There were three types of π-bonded ethylene on the surface. Recent experimental studies have suggested that ethylene is dehydrogenated on Cu(410) due to the regular step [Kravchuk et al., J. Phys. Chem. C, 113 (2009) 20881]. However, neither the formation of di-σ-bonded ethylene nor dehydrogenation occurred on Cu(210). |
